Khloe Kardashian thanks Tristan Thompson for changing her life

Dec. 12 (UPI) -- Khloe Kardashian says boyfriend Tristan Thompson has changed her life.

The 33-year-old television personality dedicated a sweet post to the 26-year-old NBA star Monday amid rumors she's pregnant with their first child.

Kardashian shared a photo on Instagram of herself and the Cleveland Cavaliers player kissing. The picture was taken at her surprise birthday party in June.

"The day I met you, my life changed. Thank you my love!" she captioned the snapshot.

E! News reported in September that Kardashian and Thompson are expecting a baby, although the couple have yet to confirm the news. Kardashian plans to give birth in Los Angeles, according to People.

"Khloe wants to give birth in L.A. That's the plan right now," a source said this week.

"Khloe seems very happy," the insider added. "She doesn't really talk about the baby. She hasn't had a baby shower yet, but has one scheduled."

Kardashian and Thompson, who already shares 1-year-old son Prince with ex-girlfriend Jordan Craig, were first linked in October 2016. Kardashian said in the Aug. 13 issue of You that her relationship with Thompson is the "best" she's ever been in.
