There was a boy band crossover recently at The Grove in L.A.
Backstreet Boy – and expectant papa – A.J. McLean was spotted chatting up former ‘N Sync star Lance Bass in the lobby of the outdoor mall’s cinema complex just after midnight.
“They were smiling and seemed excited to chat,” an onlooker tells PEOPLE. “It didn’t seem like anyone else really noticed them.”
The source adds that McLean – sporting jeans and a cap – and Bass were there with a group of people.
