Beyonce Knowles and husband Jay-Z watch from the stand as Novak Djokovic beats Rafael Nadal in the US Open final in New York. Sept. 12, 2011

*Jay-Z and Beyonce took in Monday’s big Novak Djokovic/Rafael Nadal match at the Men’s Final of the US Open in New York.

Several hours later, Will Smith and Marc Anthony were busy trying to downplay the intertwined rumors surrounding their respective relationships with Jada Pinkett Smith and Jennifer Lopez respectively.

Jay-Z and Beyonce have been getting their world travel on since the singer announced her pregnancy at last month’s VMAs in Los Angeles. They have since been spotted in Italy celebrating Beyonce’s 30th – and are now back in New York. Smith and Anthony, meanwhile, are using visuals to try and squash rumors that their families are feuding. The men took pictures together in a luxury box at the Miami Dolphins game against the New England Patriots.

Marc and wife, Jennifer Lopez, announced they were splitting up in July, and it was only a few weeks later when reports surfaced saying Will’s marriage to Jada Pinkett Smith was also on the rocks. Despite the fact that Will and Jada were quick to deny the reports, [with another photo op of the two dining at Malibu’s most notorious spot for lurking paparazzi] it wasn’t long before the rumor mill started turning that Marc and Jada, who starred in the television series “HawthoRNe” together, may have been more than just co-stars. Those reports were also quickly denied.
