Trainwrecks make strange bedfellows – so to speak, that is. I’m not suggesting there’s anything of the romantic nature going on between Britney and Mel Gibson, because–ewww! He’s married and about 30 years older than her. Plus, he’s got like 45 kids and Brit can’t even handle the two she has.

No, nothing shady going on there–just some good old, vacation-time fun! That’s right: Brit Brit and Mel–along with her father and his wife–have gone on holiday together. The foursome are heading to Costa Rica, where they’ll stay at Gibson’s house for a few days. I bet it’s a great house. I’m sure the bar is well-stocked. What?

The two have apparently been pals for a little while, with the first sighting of them taking place back in March, when they had dinner together at a Russian restaurant in Studio City. At the time a source told People magazine that they had met up a few times since Brit’s February “issues.”

“Mel and his wife Robin clearly saw a woman in crisis and wanted to extend themselves in any way possible.”

They also used to be neighbors when Britney was living in Malibu and the source said there’s no agenda behind the friendship, just “one neighbor reaching out to another.”

Well, that’s just great. My neighbor keeps me awake at 3 a.m. with his guitar playing, while Brit’s neighbor takes her to Costa Rica.

Life really isn’t fair.
