LeAnn Rimes Swimsuit model Malibu tan

LeAnn Rimes is gearing up for her big day on Sunday ... No, not the VMA's, her birthday!

The super sexy singer-actress did a little shopping, grabbed lunch at Taverna Tony's in Malibu and headed out for a facial ahead of her 29th birthday.

LeAnn's been busy racking up frequent flier miles, jetting back and forth between LA and Chicago where her hubby Eddie Cibrian is shooting the new NBC series Playboy. In fact, on her way back to LA the other day, Rimes Tweeted: "Love you Chi Town, but I'm headed back to the motherland LA for my bday w/ the fam & friends! Ahhh, I can't wait!"

And we can't wait to show you our pix of LeAnn celebrating early last night at Red O Mexican restaurant in West Hollywood. Stay tuned for those and video of the paparazzi singing happy birthday to the birthday girl!
