After Breaking Celebrity News revealed exclusive video of Amber Portwood kissing a mystery man, she confirmed she is in a new relationship. But after years of defending her controversial ex-fiancé Matt Baier, she's at it again with her new man.

Portwood, 27, was caught on camera kissing and holding a mystery man in Indianapolis, Indiana on August 7. The video comes only months after her split from Baier.

The MTV star received backlash over social media, as followers accused her of moving on from Baier too fast.

“There’s nothing wrong with dating over 3 months after breaking up with someone… crazy how people judge and are so quick to talk s**t?” Portwood tweeted.

She then gave more details on her mystery man.

“He’s 33,” she tweeted, adding of his cowboy hat, “He wore that hat as a joke you uptight idiots lol he’s from Cali.”

Viewers will meet Portwood’s new boyfriend on the upcoming season of TMOG, as an eyewitness told Breaking Celebrity News they were filming for the reality show.

Although the mother of Leah, 8, received backlash from fans, her ex-fiancé is supportive of her new relationship.

“The most important thing is Amber is happy and safe,” Baier, 46, told Breaking Celebrity News. “Amber and I were inseparable for over 3 years and we built a life together. When you love somebody that much, all you want is for that person to be happy. I support all good decisions Amber makes.”

Although he “wishes her new relationship well," he admitted learning of her new romance has been hard.

“It’s over forever so there is going to be a degree of sadness,” he said. “But Amber and I are very close still, we have always been the best of friends. So she knows I am always here if she needs me and has my support.”

It seems Baier has moved on too, as he wrote, “Road trippin’ with #bae” on Twitter.

Portwood dumped Baier, who she dated for over three years, in May when he failed a lie detector test after cheating rumors surfaced.
