Zac Efron is burning up movie screens in Charlie St. Cloud, and now he's burning up our computer screens with this sexy new cover shoot for Details magazine and the accompanying interview in which he talks about his un-Hollywood relationship with Vanessa Hudgens and his date with Tom Cruise!

Despite getting pressure from friends to play the Hollywood field, Zac seems content to hang at home with his girlfriend of four years, Vanessa Hudgens. "It’s exactly how it should be. It’s real," Efron says.

But even though he's not wanting to date around, he did accept a date from one of the most famous celebs on the planet: Tom Cruise.

The two met in very Hollywood fashion -- in the lobby of their agents' office. Tom approached Zac, asking, "You ride motorcycles?” When Efron said no, Tom asked, “You wanna learn how?” That's when Cruise invited Zac over to teach him how an engine works and show off his extensive collection of bikes, including the Triumphs he rode in the Mission:Impossible movies. When asked why he thought Cruise did that, Efron said: “I don’t even want to know. It’s just so cool that he gave a sh*t, the fact that he cared at all. No one else did that.”

You can check out the behind-the-scenes footage from Zac's cover shoot below:

Legendary rocker Rod Stewart and wife Penny Lancaster are having their second baby together.

Stewart, 65, and Lancaster, 39, have been together for the past 10 years, and this past June, celebrated their third wedding anniversary.

Stewart's rep released the following statement about the bun in the oven:

"Penny and Rod were lucky enough to be celebrating more than just their third wedding anniversary in June, as the news came that Penny was pregnant with their second child."

Their son, Alastair, was born in 2005. Stewart has five kids from previous relationships ... Kimberly, 30; Sean, 29; Ruby, 23; Renee, 18, and Liam, 15.

Samantha Ronson looked sad and lonely last night while out celebrating her birthday solo in Los Angeles.

The DJ had been spending time with her ex, incarcerated starlet Lindsay Lohan, in the time before she went to rehab, both in the sober house, and at Lynwood, which prompted rumors of a reconciliation between the two.

But now that Lindsay's at UCLA for the next few months, with only immediate family able to visit her, is Sam feeling sad and lonely?

He may only be 16, but Justin Bieber is already a music sensation, and now he's the author of a new memoir about his rise to fame, titled, Justin Bieber: First Step 2 Forever: My Story, and we've got the first look at the book cover!

The "100% Official" book features a dreamy photo of Bieber on the cover, with a personal message from the Biebs himself: "Lots of exclusive photos just for you. Love Justin xxx."

The book, which includes intimate moments from Justin's tour, as well as some dish on his personal life, drops in October.

Rumored co-star couple Ian Somerhalder and Nina Dobrev, who each took home a few surfboards at the Teen Choice Awards last night, jetted off from LAX together after winning the awards.

Vampire Diaries won Choice TV Show: Fantasty/Sci-Fi, while Nina scored surfboards for Choice TV Actress: Fantasy/Sci-Fi and Choice TV Female Breakout Star. Ian won for Choice TV Villain.

The twosome were not joined by co-star Paul Wesley, who also won Choice TV Actor: Fantasy/Sci-Fi and Choice TV Male Breakout Star, which makes it seem even more like they're dating on the DL!

Well, whether or not they have great chemistry offscreen, they certainly are amazing together onscreen!
