Kendra Wilkinson is said to be heartbroken and distraught amid reports that her marriage to Hank Baskett is in turmoil, her brother claims.

Colin Wilkinson, who was once estranged from the former Playboy model, recently spoke out about his famous sister's marriage after transgender model, Ava Sabrina London, accused Baskett of having an extramarital affair. Wilkinson, 29, and Baskett, 31, have not publicly responded to London's tryst allegations, but Colin believes there may be some truth to the YouTube model's claims.

"It's upsetting — I mean, that's my sister. I could see him cheating on Kendra … Me being around him for so long. I could probably see him doing something like that. I wouldn't have guessed a tranny, though," Colin reportedly told Star magazine.

"She definitely thinks it's true," he revealed. "She was bawling her eyes out. She told me that she's lost everything."

In recent weeks London, 25, came forward claiming he had an affair with Baskett back in April and that he was paid by the former NFL star to keep quiet.

Wilkinson, who gave birth to her second child five weeks ago, was pregnant at the time of the alleged affair.

"If the rumors are true, I honestly hope she does," Colin said. "I mean, a man runs to another male because obviously he has gay tendencies."

Wilkinson shares a newborn daughter Alijah and 4-year-old son Hank IV with Baskett. The couple wed in 2009 and their marriage is played out on their WE tv reality show "Kendra On Top."

"She believes that the accusations are true, that he met with this transexual in question, but also believes that it was a one-time thing," a source told "She is not against it, she is just mad that it is out and it embarrasses the family. So she is mad at him but they will not break up over it."

On Tuesday one report claimed the mother-of-two "flipped out" after "snooping" and uncovering evidence relating to the alleged affair. A source claims Wilkinson punched walls in their Calabasas, Calif., home, before flushing her wedding ring down the toilet, however, this report has not been verified.

"She thought it was ridiculous [but when Hank didn't try to clear his name] she became suspicious and started snooping," a source told Us magazine. "She was extremely angry."

On Wednesday the reality TV star was photographed without her wedding ring.
