In Denial? Sandra Bullock Ignores Friends' Concerns Over Bad Boy Love Bryan Randall's Past: Arrests, Drugs & More!

Is Sandra Bullock headed for heartbreak yet again? Insiders tell RadarOnline.com that ever since the dark past of her boyfriend, Bryan Randall, has been revealed, she's steadfastly been ignoring friends' concerns about their relationship.

The couple should be enjoying the newness of the relationship but Bullock's pals are "obviously very concerned Bryan is cut from the same cloth as her ex-husband, cheater Jesse James," an insider told RadarOnline.com. "Bryan has a very tough guy persona, and can come across as extremely arrogant."

"Sandy's friends are also concerned about Bryan's criminal past and allegations of drug and alcohol abuse," the source said. "Even though he has told Sandy he is sober and has been for years, the friends are on their guard."

"Bryan was up front with Sandy as they got more serious, and told her everything that was scandalous in his past," the source said. "He explained that he had to really grow up and become responsible to raise his daughter, Skyler, alone, and he insisted that all his trouble is in the past."

"The problem for Sandy's pals is that is exactly what Jesse told her!" the source explained. "He had a young daughter at the time, Sunny, and Sandy and Sunny became very close. The similarities between Bryan and Jesse are just eerily similar. Sandy has always been attracted to the bad boys."

What exactly has the friends on alert? As RadarOnline.com reported, Randall's neighbors previously accused the single father of smearing dog feces on their door during a dispute.

"I filed a police report the next morning for criminal threats …" the neighbor claimed in court documents requesting a restraining order. "I know he has guns and a notoriously erratic temper and I am scared of what he will do next, as his daughter will be gone come Sunday."

The National ENQUIRER also recently uncovered court documents revealing Randall had a felony charge for driving on a suspended license, which was reduced to a misdemeanor and an unspecified fish and game violation.

Randall also has several mug shots from his criminal arrests, looking less than camera ready.
