Khloé Kardashian is a mum [1]! The 33-year-old reality TV star and boyfriend Tristan Thompson [2] welcomed their first child together, a baby girl, at a hospital outside of Cleveland on Thursday morning, TMZ reports. No other details have been released at the time.

Khloé and Tristan first met during a blind date and struck up a romance in September 2016. After much speculation [3], the reality TV star confirmed that she and Tristan were expecting in December 2017 when she debuted her bare baby bump [4] on Instagram. Khloé later revealed that she was having a girl on Keeping Up With the Kardashians and celebrated with a dreamy baby shower [5] filled with pink flowers and balloons.

The arrival of baby Thompson is likely bittersweet, as rumours that Tristan cheated on Khloé [6] have recently come to light. On Tuesday, The Daily Mail shared footage of the NBA star reportedly kissing a mystery woman at a nightclub in NYC. Shortly after, TMZ published a video of Tristan making out with two different women at a hookah lounge in Washington D.C. back in October 2017. While both Khloé and Tristan have yet to publicly address the reports [7], "her family is rallying around her" and "her sisters are being super supportive of her."

Baby Thompson is the first child for Khloé, who joins Tristan's 1-year-old son Prince from a previous relationship.
