“They are absolutely thrilled,” a source revealed to PEOPLE in September of the couple. “This isn’t something they were in a rush to announce to the whole world, and it’s only been in just the past week or so that they’ve felt comfortable telling most of their inner circle.”
“This is something Khloé has wanted for years and years and yet it’s more than that: She didn’t want it unless she was in the right relationship for it,” the insider said, adding, “This is such a wonderful moment for her: not only is she going to be a mother, she is going to be raising a child with a man she truly loves. Everyone is over the moon for them both.”

Kardashian isn’t the only one in the family expecting a child. Her pregnancy news came days after sources confirmed to PEOPLE that sister Kylie Jenner and boyfriend Travis Scott are expecting a baby girl. She is due in February.
Sister Kim Kardashian West and husband Kanye West are also expecting their third child — a daughter — after hiring a surrogate to help them expand their family.
Jenner, 20, has yet to confirm her baby news, while a Dec. 13 Keeping Up with the Kardashians trailer teased that the family may finally reveal Kardashian’s baby news. Kardashian West, 37, spilled the beans about her little one on the way in the 10-year-anniversary season trailer for the show.

Kardashian and Thompson, a center/power forward for the Cleveland Cavaliers, first stepped out together in early September 2016 and have been spending much of their time together since then in Cleveland — even celebrating Halloween, Thanksgiving and Christmas there together last year. They then rang in 2017 in Miami with one another.
Ahead of Thanksgiving this year — which she hosted in Cleveland — the star used website and app to share some of the things she’s grateful for. “Believe me, I know how truly blessed I am,” Kardashian said. “I thank God every day for this life. It’s important to remember your blessings all year long, but Thanksgiving is a good time to take a moment and be appreciative.”
Of course, it comes as no surprise that Thompson is top of the list. “I am truly grateful for Tristan and all that he has brought into my life!” she praised the Cleveland Cavaliers player, whom she has been dating for over a year. “He has been a huge positive influence on me and has given me a new level of happiness and love.”

Though Kardashian and Thompson aren’t yet engaged, the Revenge Body star opened up to ES Magazine in April about the possibility of tying the knot with the sports star — admitting she would say yes if he popped the question and is excited about the prospect of starting her own brood.
“I would love to have a family. We’ve talked about it. He [already] is a father, and I know for a fact that he would be an impeccable father,” she revealed.
“I definitely want to be a mom. But I don’t put the pressure on it. It’s not like, ‘The clock is ticking.’ I feel in my soul it will happen.”

It was first reported in October by UsWeekly that she was with child.

Her youngest half sister Kylie is also reportedly pregnant with a baby girl, but has yet to comment. The father is believed to be Travis Scott.
And her older sister Kim has a baby girl due via surrogate in January 2018, which will be her third child with husband Kanye West after North, four, and two-year-old Saint.

Her brother Rob has a one-year-old daughter Dream with ex-partner Blac Chyna.

During a June episode of KUWTK, Khloe learned that she had fewer follicles, which hold eggs, than expected for a woman her age, which would suggest she would have trouble conceiving.
However, the reality star's follicle count returned to normal once she came off birth control.
Khloe revealed during the same episode that she 'fake tried' to get pregnant with ex-husband Lamar Odom, 38.
Third child: Kanye West and Kim Kardashian, shown last month in Hollywood, are expecting their third child together via surrogate
The reality star previously said she took hormone therapy and tried to get pregnant with Lamar via IVF.
In a May 2013 interview withRedbook, Khloe addressed her difficulty with falling pregnant during their marriage.
'People assume I’m desperate for a baby. And yes, I would love to have a baby,' Khloe said. 'But I’m 28, and I’ve been married three and a half years. I love my life, but it doesn’t feel incomplete right now,' she said.
It's been almost a year to the day since Khloe was granted a divorce from retired professional basketball player Lamar.
After initially filing in December 2013 following four years of marriage, Khloe filed for divorce for a second time in May 2016 and it was finalised at the start of December.
More to come: Kylie Jenner, shown in April with boyfriend Travis Scott in Houston, also reportedly is pregnant
She called off her divorce in October 2015 following a near-fatal drink and drugs overdose at a brothel in Las Vegas.
Lamar was hospitalized and placed on life-support, when he was discovered unconscious at the famed Love Ranch brothel during a four-day binge and Khloe rushed out to be with him.
The couple met, fell in love and married after a whirlwind month together back in 2009, and their hasty marriage and relationship was witnessed by fans on Keeping Up With The Kardashians.
Lamar later admitted to having 'multiple affairs' during his marriage to Khloe and in March recalled how he got into a 'dark place' with cocaine-use.
Divorce: Khloe was married to retired basketball player Lamar Odom (here in 2011) for four years until their divorce was finalised last December. She previously revealed that she was 'desperate' for a child during their marriage but had trouble conceiving
Stand by your man: Khloe briefly called off her divorce from Lamar in 2015, when he was hospitalised for a near-fatal overdose (here together in February 2016, following his recovery)
He said: 'When I became Khloe Kardashian's man and on TV, it made me look more enticing.
He added: 'If there is one thing I regret when I was married, it was having multiple affairs with different women. That wasn't the stand-up thing to do. I wish I could have kept my d*** in my pants.'
He went on to explain his drug use, saying: 'I was in a very dark place and very confrontational. I wasn't trying to repair my marriage; I was just trying to get high. My life was all about drugs at that point.'
KHLOE Kardashian has finally confirmed her pregnancy.
The Keeping Up With the Kardashians star, 33, is expecting her first child with NBA basketballer Tristian Thompson.
In one of Hollywood’s worst-kept secrets, Kardashian, 33, shared a photo of her baby bump for the first time today ... finally confirming she is expecting.
