Britney Spears was in Mexico for a few days staying at the Four Seasons Pita Maha resort in Puerto Vallarta with her ever-present “cousin” Alli, who is most likely the help. She strutted her stuff in a scary low cut g-string and the roots of her braided on extensions were clearly visible. At one point her cover-up flew up to reveal her dimpled butt. She’s not in terrible shape, but she shouldn’t really be showing it off, either.

There’s a questionable story that Britney plans to visit Lohan in rehab, and that she was encouraged by Lohan’s slutty lover, Calum Best. Best is said to have asked Britney to contact Lohan, and since Britney knows the people at Promises and “successfully” completed her own stint there recently, she can show her around.

Probably aware that he isn’t the best role model for sobriety, the sometime model and professional playboy turned to Britney for help.

A source tells the Daily Star, “Calum was quite brave calling Britney as he only met her briefly a few years ago but when her people told her he’d been in contact, she was happy.

“Calum said he was worried that Lindsay would be so lonely at Promises that she wouldn’t benefit from the treatment at all. Britney’s now in such a good place that she said she’d be happy to visit and to introduce Lindsay to some of her friends there.”

The article goes on to say that Calum wants to get back with Lohan and that he’s renting a condo near Promises in Malibu to be closer to her. I call bullshit on that one, as the Daily Star isn’t that reliable a source, and Britney is said to dislike Lohan. She even was rumored to have barred her from the VIP section at one of her comeback shows.

Still, I wouldn’t put it past Britney to show up at Promises to steal some of Lohan’s rehab thunder.

Meanwhile Britney’s mom, Lynn Spears, is scheduled to appear on the now even more boring “The View” on Wednesday. Everyone is wondering what she’ll talk about since she is said to be estranged from Britney, who didn’t even visit her when she was stricken with pneumonia and was laid up in the hospital on Mother’s Day.
