Casper Smart and Jennifer Lopez
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
"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.
