Beyoncé reignited pregnancy rumors Monday after she was spotted leaving her Super Bowl rehersal sessions wearing an oversized green jacket. The "Drunk In Love" singer's outfit gave rise to speculation that she may be trying to hide a baby bump.

The singer was reportedly at the McKay Athletic Center on the University of Southern California campus in Los Angeles practicing for her upcoming Super Bowl 50 halftime show with her squad.

"Her dancers were dancing and rehearsing," a source told E! News. "They blocked everything down and the windows so nobody could see."

Lately, Beyoncé has been wearing a lot of loose, figure obscuring clothing leaving fans wonder if Blue Ivy will soon become an elder sister.

Last week, Beyoncé stepped out for a dinner date and Golden Globes after party in Los Angeles where she sported her outfit with a military jacket that featured a customized paint-splattered print. During her outing, the 34-year-old singer reportedly appeared to be trying to hide her stomach and also kept her arms firmly crossed over her stomach.

The "Crazy In Love" singer's change in dressing style sparked rumors that she may be expecting her second child with husband Jay Z. 

Beyoncé is also set to perform at the Super Bowl alongside Coldplay at Levi's Stadium in Santa Clara, California, on Feb. 7.

"Beyoncé has been in the talks to perform for sometime but it was all top secret," another source told E! News. "Beyoncé is very excited to be at this years big Super Bowl. She can't wait."

The insider reportedly added: "Performing in the past at the Super Bowl was one of her favorite performances. She loved the energy of the crowd. She is a big fan of Coldplay and thinks it's going to be a fantastic performance by both of them."
