Los Angeles, California - Khloé Kardashian is now a mother of two after she and Tristan Thompson welcomed a new addition to their growing family!

The baby boy, whose name has yet to be revealed, was birthed via a surrogate. He will be the young brother to the couple's 4-year-old daughter, True Thompson.

Khloé and Tristan have been in an on-and-off again relationship for some time now, with the flip-flopping mostly due to the NBA star's constant habit of cheating.

After announcing they were expecting in July, videos of Tristan partying in Greece with other women began making the rounds on social media, with fans relentlessly slamming the athlete.

Back in December, it was also revealed that Tristan was expecting a child with a fitness model from Texas, after the woman filed a lawsuit for child support. He attempted to hide and cover up the affair, but failed miserably.

Despite his infidelities, Khloé shared in the last season of Keeping Up with the Kardashians how she was adamant about conceiving another child using fertility assistance and co-parenting with Tristan.

While Khloé and Tristan seem to have a bit of a messy relationship, a new baby tends to focus minds, so maybe things are finally about to change.
