Eyebrows shot sky-high this week after snaps surfaced of a bikini top-clad Lindsay Lohan energetically shaking her moneymaker during a weekend shindig at the Coachella Music Festival. Sure, she looks like she's having a blast in the "wild new pix!" (per the cover of the latest Star), but she also appears (at least to us) a wee bit party pooped, which has us worried about what's gonna happen on July 2.

That's the day the rehab grad hits the big 2-1 and can legally enter all those hotspots she's been frequenting for so many years. And while we'd hoped that Linds, who's already experienced more in her first two decades than many do in a lifetime, would mark the occasion with a quiet meditation of her frenetic life thus far, she has other, less contemplative plans in mind.

"I'm going to milk it because it's a big birthday," the socially inexhaustible starlet enthused to a bedridden Ellen DeGeneres on Wednesday. "I think I'm doing a party in Vegas, which makes sense because I've never been able to go out there. I have never gambled there."

And as Lohan's accountants scramble to secure her assets ahead of her Sin City celebration, she's trying to quash rumors about her revolving-door love life.

When E! Online recently asked her how much of the chatter about her is based in fact, she said, "Some percent is true, but I'll admit it if it's true. There's a lot of things out there now that aren't true."

While she declined to say specifically what was fiction, LiLo seemed to allude to tabloid talk linking her to DJ pal Samantha Ronson as she fumed there are "silly things" said about her, including "that you can't have friends who are girls. It's ridiculous."

Speaking of ridiculous, that's the best way to describe this tidbit from the London Daily Mirror, which alleges Lindsay got the cold shoulder when she attempted to engage Arctic Monkeys frontman Alex Turner in a conversation at a recent bash in Los Angeles.

The paper claims the rebuffed Lohan left "in a huff," which cleared the way for frenemy Paris Hilton to take a stab at chatting up the band. Alas, the self-adoring starlet's attempts also failed, but her onetime BFF Kimberley Stewart purportedly had better luck.

"Lindsay was really miffed when Alex was unresponsive towards her and had a face like thunder. But it was a different story with Kimberley," Stewart a mole tells the tab. "Matt was following her around like a lap dog."

And finally, even though Lindsay recently told Nylon that she "wouldn't ever want [the paparazzi] not to take my picture," that hasn't stopped her from taking aim -- literally -- at the shutterbugs.

The New York Daily News reports she poses with a gun in her hand for the cover of the June/July issue of Radar magazine, which features her pistol-packing pose under the headline, "Hollywood vs. the Paparazzi: It's War!"
