Young man of the hour Shia LaBeouf and his beautiful, raven-haired Transformers co-star Megan Fox both turned 21 this year. She celebrated at a Maxim magazine party and Shia went to a cigar lounge in Beverly Hills to smoke and have a little scotch to celebrate legal drinking age. As for relationships; Megan is engaged to former "90210" star Brian Austin Green and Shia says, "I'm just dating and messing around. I'm 21 years old [so I'm] doing the 21-year-old thing".

We got the up close and personal scoop on these two in Beverly Hills recently when we interviewed the duo about their experiences on their new summer blockbuster film. At L.A.'s Four Seasons Hotel, Shia was relaxed in brown shirt over a tee and jeans. Megan accessorized her dark outfit with a gold cuff encrusted with diamonds.

In a casual chat, we learned everything from Shia's feelings about his big role in the long-awaited new Indiana Jones film and the fact that he had tons of fun driving a hot car on the Transformers set to his non-participation in partying young Hollywood. Megan told us about an on-set injury and what it's like pretending something huge and metal is standing in front of you when it's really just a tall stick. We even found out which movies the two remember as summer date flicks when they were younger. We sit down and can't help but notice that this hot girl has a tattoo of Marilyn Monroe! Wazzup with that?
