Beyoncé and Jay-Z, dancing in their seats as Alicia Keys and Sade performed "Love Is Stronger Than Pride" at the Black Ball in New York, benefitting the Keep a Child Alive foundation. And Knowles kept on dancing as her hubby took the stage to perform his big hit, "Empire State of Mind," alongside Keys. When she was done performing with the rapper, a pregnant Keys received a big hug from new hubby Swizz Beatz, who was waiting for her off-stage.
She may be in New York to promote her new movie, Life As We Know It, but Katherine Heigl was also playing supportive wife. The actress cheered during her hubby Josh Kelley's concert at Terminal 5, even singing along to his single "Georgia Clay," and jamming during Miranda Lambert's's set.
Kristin Cavallari and her Chicago Bears beau Jay Cutler, celebrating his team's strong season at Stay Lounge in Chicago. The couple was accompanied by friends but, a source tells us, "they were cuddly with each other – nestled really close, and they left together."
Are they back on? Bobby Cannavale and Annabella Sciorra, enjoying the tasting menus at Spiaggia in Chicago, and sitting in a romantic booth overlooking Lake Michigan.
