ROBERT IRVINE is getting people buff in Philly for the Food Network.
My spies spotted the "Restaurant: Impossible" host at the Sporting Club at the Bellevue last week working out with a hefty partner.
Sources tell me that Irvine is working on a new show called "Fitness: Impossible" that will get a Food Network debut next month. I hear it's "a cooler version of 'The Biggest Loser.' " The show is being filmed all over with Philly, Bucks County and New Orleans as locations.
Irvine regularly works with Philly-based companies Marc Summers Productions (you know Summers from his regular shows on the Food Network and "Double Dare") and Alkemy X (formerly called Shooters), both of which are repped by Cozen O'Connor lawyer Justin Wineburgh.
* Will Smith was seen watching his beloved Sixers lose to the Grizzlies on Saturday at the Wells Fargo Center. Best part? Smith was caught on the Carlton Cam, an ode to Smith's former, fictional "Fresh Prince of Bel Air" cousin Carlton Banks (played by recent "Dancing with the Stars" victor Alfonso Ribeiro). Smith is currently camping out in Pittsburgh, where he's starring in a movie about football-related concussions.
* Eagles cornerback Cary Williams celebrated his 30th birthday at Ruth's Chris Steakhouse (260 S. Broad St.) with some buddies on Friday night. I hear there were about 18 people celebrating with him including teammates Darren Sproles, Malcolm Jenkins and Bradley Fletcher, and his wife, Amanda Williams. I hear everyone was incredibly nice and Williams is quite a generous tipper, even if he was the birthday boy, leaving a whopping 90 percent tip on a $1,500 tab.
* Before Nick Jonas played the Jingle Ball, the pop hunk walked along Passyunk Avenue, dining at Cantina Los Caballitos (1651 E. Passyunk Ave.) before being recognized by some Santa-hatted ladies who were quite excited to see the Jonas Brother.
* Also in town for the Jingle Ball: "All About that Bass" songstress Meghan Trainor was spotted at the Hotel Monaco (433 Chestnut St.). I hear she stayed in the Majestic Suite.
* NBC10's Keith Jones, Fox 29's Caitlin Roth and CBS3's Syma Chowdhry went head-to-head at NRG's Home Gingerbread House Decorating Contest on Friday in Christmas Village. Chowdhry took home gingerbread glory, decorating her way to $2,000 for Red Paw Emergency Relief.
Phish frontman Trey Anastasio gave a shoutout to his beloved Flyers during Saturday night's solo show at the Tower Theater (19 S. 69th St., Upper Darby). During the song "Ether Sunday," Anastasio improvised after the real lyrics, "This much, I pray, it's true," adding "The Flyers are going to win the Stanley Cup this year," while the band echoed, "It's true." Princeton, N.J.-raised Anastasio also told the crowd, "This was a great night, and it was even greater because the Flyers won today!"
My colleague Chuck Darrow hit up Parx Casino (2999 Street Road, Bensalem) on Friday night for a celebration of storied DJ Sid Mark's 58th anniversary as a broadcaster on what would have been Frank Sinatra's 99th birthday.
Darrow told me that an unexplained technical screw-up put the kibosh on a live remote broadcast, causing Mark to throw away the script. "Instead Frank Sinatra Jr. and Philly pop-music legend Bobby Rydell spent some 90 minutes delighting the sold-out 360 Lounge crowd with wonderful show-business anecdotes about the greats they worked with," including Old Blue Eyes, Darrow said.
He added, "After the program, Mark, Sinatra, Rydell, and some friends and family members dined in the private room at Parx Grill."
