Dan Gross: Splitsville for NBC 10's Tracy Davidson

NBC 10 ANCHOR/reporter Tracy Davidson and her husband, David Tinsch, a videographer/producer, have separated, sources tell us, and the couple have placed their Ardmore home on the market for $1.1 million. "My husband and I have been together for more than 20 years," Davidson told us Monday. "We have always kept our lives private and will continue to do so," she wrote in an e-mail. Tinsch did not return a request for comment. The couple's dog, Charlie, a goldendoodle, was recently featured in the Daily News and with Davidson in a video on Philly.com. He has mega-esophagus, which makes it difficult to digest food unless he eats sitting up. The couple built a wooden box in which Charlie sits while eating. In an essay that Davidson wrote for our "Hurtin' Pup" contest, she told us that she cooks about 300 meatballs per week for the pooch.

Rollins roasted at Union League

Shane Victorino got a few laughs Monday night at a charity roast of Jimmy Rollins at the Union League. The Flyin' Hawaiian teased his Phillies teammate that his fiancée, Johari Smith, agreed to marry him only because Victorino had previously turned her down. Mayor Nutter told Rollins, only half-joking, we imagine, that he should move from Jersey into Philadelphia because the city could really use the taxes off his salary. 6ABC's Keith Russell was among others who performed at the very clean roast, which benefited Rollins' charitable foundation. Rollins himself made a $4,000 donation to the Union League's scholarship fund.

Rowand returns to old haunt

Giants outfielder Aaron Rowand, who became a Phillies-fan favorite when he broke his nose three years ago on a Citizens Bank Park fence chasing down a fly ball, went for an American cheesesteak with onions and mushrooms at Talk of the Town (3020 S. Broad) Monday afternoon. He was a regular at the sandwich shop while playing for the Phils.

Dr. Oz to be honored here

Dr. Mehmet C. Oz, better known to "Oprah" viewers as simply Dr. Oz, will be honored Oct. 2 when he receives MANNA's the Power of Nutrition Award in a luncheon at the Loews Philadelphia Hotel, in Center City. Oz and MANNA's chief executive, Richard Keaveney will speak at the event, sponsored by CBS 3, where "The Dr. Oz Show" premieres on Sept. 14. Tickets are $125 for the luncheon and available online at cbs3.com and cwphilly.com. MANNA provides nutritious meals for Philadelphia-area people suffering from life-threatening illnesses.

Mya making Dusk appearance

R&B singer Mya, who'll soon be hoofing it on "Dancing with the Stars," will perform two sets Friday night at the Dusk nightclub at Caesars Atlantic City. She'll perform at 11 as part of a private party for Cashman & Associates, the PR firm that handles the club, and again at 1 a.m., after the club is open to the public for the night. Dusk was closed last Friday night out of respect for DJ AM, a partner in the club, who was found dead in New York that day.

New leadership at Fox 29

Patrick Paolini starts next week as vice president and GM of Fox 29. He'll replace Michael Renda, who is taking the same title at Fox Chicago and WPWR My50. Paolini last worked as sales manager at Fox's New York duopoly, Fox 5 and WWOR My 9. Renda's staying on through the week assisting with the transition, which coincides with the station's Monday launch of a 6 p.m. newscast anchored by Kerri-Lee Hackett.
