Is life on the road getting to Britney Spears?
A family insider says Britney was caught by her conservator/dad Jamie Spears popping over-the-counter diet pills and washing them down with Red Bull before a performance on her Circus tour, reports gossip site Betty Confidential.
“Britney was definitely trying to get high by taking too many diet pills and energy drinks,” the source told the site. “Jamie thinks the combination of the two is making her whacked-out and, causing her to lash out in weird angry rampages.”
But that's not all. The insider said “Britney uses green-tea supplements, [Lab 88’s herbal ephedra-free] Metabo Speed XXX, Dexatrim and apple cider vinegar to control her weight and energy levels. She also pours those 5-Hour energy drinks into her Red Bulls," according to the site.
