Khloe Kardashian’s invitation for cheating boyfriend Tristan Thompson to joined her while she gave birth was just the calm before the storm. Now that she’s had her baby girl, the 33-year-old reality personality is vowing an all out legal war.

Khloe apparently can’t wait to get out of Cleveland, where Tristan plays for the NBA Cavaliers. She’s hightailing it back to her family in Los Angeles as soon as doctors give her the okay and she can arrange a private jet.

She has no plans to return. Instead she’s already lining up a legal team to fight in court for sole custody of the child.

“She’s in absolute disbelief that Tristan has done this to her daughter, and now she’s out for blood,” said a source close to the family.

Khloe was humiliated on the eve of giving birth when Thompson, 27, was spotted in a Manhattan club last weekend, making out with New York City stripper Lani Blair.

They were later spotted heading back to his hotel. Thompson was in town with the team to play the New York Knicks at Madison Square Garden.

He returned to Cleveland for another game against the Knicks Wednesday night (Apr. 12). Thompson was booed by fans and the Cavs lost.

Thompson is likely to have little or no time to patch things up with Khloe in Los Angeles. The Cavs are heading into the all-important NBA playoffs.

Tristen had practice today, according to People.

Apparently the basketball player has been cheating on Khloe ever since she got pregnant. Last October, he was spotted in Washington, D.C. with two different women. One of them now claims she’s pregnant with Tristan’s child.

Khloe gave birth around around 4 am on today, (Apr. 12) at a hospital just outside of Cleveland. Khloe had been living there with her high-rolling baller.

While Khloe was reportedly being the “bigger person” by inviting Tristan to the birth, the tension in the room must have been intense. Momager Kris Jenner and sisters Kim and Kourtney Kardashian were also there.

There’s some question whether all the drama surrounding Thompson’s sexcapades caused Khloe to go into labor early. She wasn’t due until the end of the month. But started experiencing contractions this week, according to reports.

“Everyone is focused on what’s best for their baby girl,. Khloé is being the bigger person and letting Tristan bond with their baby,” said the People source.
