Jennifer Lopez: I Was 'Freaking Out' When Son Max Needed Stitches

Sunday April 28, 2013 03:00 PM EDT

At some point every mother has to panic just a little.

For Jennifer Lopez it was when her 5-year-old old son Max was bleeding under his chin and needed stitches, the latest milestone in motherhood for the Dance Again singer.

"I hear that all little boys have a scar on their chin," she told PEOPLE of the recent mishap. "Of course, I was freaking out, but he was fine. He said it tickled."

With her son, who she calls "The Boss," recovering and spending the weekend with Lopez's ex, Marc Anthony, Lopez and beau Casper Smart headed to Las Vegas for the grand opening of mega club Hakkasan inside the MGM Grand.

"It's a little night off from being a mom and that's exciting," she said. "It's nice to have a little down time."

Inside the club, the couple cuddled at a VIP table near Vanessa Hudgens and Cheryl Burke while listening to Grammy winner Calvin Harris deejay in the main room.
