February 28 is Mianna Thomas' birthday. She's 21! Yes, finally of legal age to drink! She was just 18 when we first photographed the mindblowingly stacked Mianna. How soon they grow up. The super-titted natural wonder lives in the party capital of the United States, Las Vegas, so she's got no shortage of places to go and celebrate. We see Mianna pose for her layout in March '11 SCORE. She is wearing a tiny pink dress that causes shock waves. Do you wonder about all this recent earthquake activity? Here's one possible reason for that. SCORE's editor sneaks into the studio to ask her a few questions and while he's there, he can't help but measure her with his trusty tape. Those 34JJ (yes, 34JJ) tits are made for wetting. He just happens to have a super-soaker machinegun handy.
