Brooke Hogan suffering a breakdown?

Brooke Hogan -- the daughter of former WWE star Hulk Hogan -- is suffering a breakdown, it has been claimed.

Friends of the Hogan family are reportedly growing concerned for 20-year-old Brooke since her 17-year-old brother, Nick, was sentenced to eight months in prison after pleading no contest to charges of reckless driving 10-days-ago.

A source tells Fox News, "She’s suffering the worst of all; she just can’t keep it together and has been hit the hardest."

The source adds that Brooke is "extremely sensitive" and her emotions are spiraling out of control.

And ever since revelations of Hulk's infidelity with Brooke's former friend; their relationship has been severely strained, though Nick's arrest "brought them a little closer to reconciliation," but the source adds it’s not the case for Hulk -- real name Terry -- and his wife Linda.

The estranged couple both appeared at Nick's hearing on May 9, where Linda even flashed her wedding ring, apparently for the first time since news of the affair broke.

The source adds, "Basically they were trying to put their best foot forward and fake a public image of unity and support for their son.

"He [Hulk] is a very astute businessman and very good at playing the media — he even admitted in court that their reality show was scripted and not so real after all."
