Khloe Kardashian has given birth to a baby girl at a hospital near Cleveland.
Sisters Kourtney and Kim, mother Kris and her best friend Malika were by her side in the delivery room on Thursday (local time), TMZ reports.
Partner Tristan Thompson was also there, amid allegations he's cheating on the reality TV star with multiple women.
An Instagram account has reportedly been started by someone claiming to be one of the basketball player's alleged mistresses, who has posted her own sex tape and claims she's pregnant to him.
Kardashian is said to be 'completely devastated' over the claims and has suggested she will raise the baby alone, an unnamed source tells Radar Online.
The sex of Kardashian's baby was not a surprise at the birth. She revealed she would be welcoming a daughter months ago, in an elaborate baby shower which aired on the family's hit show, Keeping Up with the Kardashians.
Two of her sisters have also recently given birth. Kylie Jenner gave birth to baby girl Stormi in February after managing to keep her whole pregnancy under wraps, despite swirling rumours.
Kim Kardashian has recently welcomed her third child, daughter Chicago, via surrogate after complications with her previous two pregnancies with Kanye West.
