La La, 36, was seen partying with her brother Christian Vazquez at The Borgata in Atlantic City, according to a Page Six insider.
She hung out at the tables with his group went back to her room before they headed to Scores at The Hard Rock.
She was nice enough, however, to give him $10,000 in singles to make it rain at the strip joint.
Life doesn't appear to be all fun and games for La La and Carmelo, 35, lately.
Carmelo was photographed sunbathing on a yacht with a mystery woman last month. The NBA star later denied any cheating allegations in a video he posted on Instagram.
This isn't the first time Carmelo has been accused of cheating on his wife. The couple separated in April 2017 after he reportedly fathered a daughter with a woman named Mia Burkes. They reconciled in December 2018.
They might be doing OK after all. La La and Carmelo were photographed grabbing sushi together in Beverly Hills last week.
