Entourage star Jeremy Piven looked buff on the beach in Malibu on Saturday, but he's ruining that healthy physique by smoking a cigar (check out his right hand)!

And, smoking on the beach is illegal in California! There's nothing gold about that, Ari!

See a close-up of Piven smoking his stogie after the jump.

The stars of HBO's Entourage hit Mastro's Steakhouse in Beverly Hills Tuesday night only hours after they filmed the last scenes ever of the series.

The show's eighth and final season debuts July 24.

At the restaurant were Adrian Grenier, Jeremy Piven, Jerry Ferra, Carla Gugino, Camilla Belle, Steve Harvey, Vince Vaughn, Beverly D'Angelo and Scott Caan.

The stars took to Twitter to mourn the show. Grenier wrote, "I don't know what I'll miss more, the laughs or the love." Ferrara Tweeted: "It has been the time of my life."

Too sweet! We'll miss you, guys! Check out all the pics from the party in our gallery below ... including a photo of slimmed-down Jerry's hot new girlfriend!

Jeremy Piven and Miley Cyrus are new BFFs. Say it isn't so!

The Entourage actor, 45, and the former Hannah Montana star, 18, became close friends while filming their movie So Undercover in New Orleans.

While promoting his latest film I Melt With You at Sundance, Piven tells E! News:

"I think I must be an 18-year-old girl because we got along really well. It was just so much fun. I had so much fun with her and we had great chemistry. It was really really weird -- we're like polar opposites."

As for Miley's recent controversies, including her salvia incident last year, Piven adds:

"You know, you can judge her, but what were you doing when you were 18? She's kind of amazing. There's something so incredibly refreshing about someone who is exactly who they are. There's nothing pretentious about her. She's this force. She loves to laugh."

Um, ok. I guess the old saying is true ... opposites attract.

Entourage star Jeremy Piven celebrated his 45th birthday a few days early at Bardot last night, and the actor looked like he was having a blast getting his party on. He may not be Ryan Phillippe in the looks department, but he looks pretty good for his mid-forties!

Thank goodness he didn't go shirtless!

Yesterday we spotted our favorite moober sweating it out in Malibu, and the actor gave us a peek at his abs as he jogged by photogs. Okay, he doesn't look that bad, and at least he's making an effort to stay fit!

Jeremy Piven and his flavor of the week hit the beach in Malibu, and I'm not sure why she's wearing a nude push up bra instead of a bikini, but at least she's distracting us from Jeremy's rack!

He did us the courtesy of rocking a tank top so we can't be too mean, but if you've seen the Piv shirtless before, you know what we're talking about!

We ran into Mr. Ari Gold himself on Robertson yesterday afternoon (I KNOW), and while he didn't spill that many deets about the upcoming season of his hit HBO show, he did reveal that shooting starts in just two weeks!

I know I'm not supposed to find him sexy, but I just adore him so much! Is that wrong?

Whoa - new couple alert? I wonder! When Entourage and Nip/Tuck collide! Jeremy Piven and Kelly Carlson were spotted leaving Madeo last night, albeit separately.

I can actually see these two together! Hot or not?
