In town for Lollapalooza festivities, Kellan Lutz
stopped by Miami lounge in Chicago, where he was able to sneak in some downtime with his brothers and close pals.
Lutz and his crew immediately made their way to the Barefoot Wine & Bubbly bar where they "quickly started chatting up several adoring ladies who were professing their love," a source tells PEOPLE.
"The actor talked to the girls about his upcoming Expendables 3
role and even did an impression of his costar, Arnold Schwarzenegger."
But after his new pals picked out some Polaroid sunglasses for Lutz to model, the onlooker says the former Twilight
actor – who has most recently been publicly dating
Sharni Vinson – "brushed off the female attention and seemed much more into hanging out with his guys."
