Kate Upton is hot off her break up with "Dancing with the Stars" pro Maksim Chmerkovskiy but that's not keeping her from doing the Cat Daddy Dance on the town. Kate was at the Sports Illustrated Swimsuit Issue anniversary party. Upton was also seen over the weekend with her ex-boyfriend, Detroit Tigers pitcher Justin Verlander. Spottings of Kate Upton and Justin Verlander stirred up romance rumors all over the net.

On Saturday, 21-year old bikini model Kate Upton and the baseball star Justin Verlader, 30, were photographed at the Wells Fargo Arena in Philadelphia while they were taking in the Philadelphia Flyers hockey game against the Tampa Bay Lightning.

One Flyers fan posted a pic of the couple on the Twitter with the caption "Kate Upton and Justin Verlander at the flyers game in the box seats next to ours."

The Philadelphia Inquirer reported that Kate Upton and Verlander went to Del Frisco's for a bite with friends before the game. A witness said "[Upton] kept it low key, opting for not-much make up. Many people dining near her didn't even recognize her. I hear Upton and party dined on the calamari and the cheesesteak dumplings, as well as a bottle of cab that got dropped off at the table."

But they're not back together. A source said "Kate and Justin are not back together." Upton was just keeping his spirits up before a planned surgery. The source said "She wanted to be there for him".

Verland got surgery for a  muscle injury during he suffered during his offseason conditioning program last month. Verlander recovering in a Philadelphia hospital. He will have to go through six weeks of physical therapy. The pitcher says he will be ready to play at the beginning of the 2014 season.

At a press conference the Detroit Tigers manager announced "Despite the fact this is a little bit of a setback physically, his previous workouts will probably allow him to catch up to speed much quicker."

Upton and Verlander were rumored to be dating last year after taking a romantic Caribbean vacation together over the New Year in 2013. Kate never confirmed the relationship publicly.
