From On the Road to the dance floor!
Kristen Dunst celebrated a friend’s birthday at Bootsy Bellows in West Hollywood on Thursday night.
Arriving around 10 p.m., the Bachelorette star glowed in a black dress and high heels as she and friends mixed vodka cocktails in the VIP area.
Dunst disappeared for a few minutes, only to return quickly with her beau Garrett Hedlund, who was dressed comfortably in a T-shirt and jeans. The couple was anything but shy about their affection, sitting closely and sharing quick kisses.
At one point in the evening, the On the Road costars took to the dance floor as Lauryn Hill’s “Can’t Take My Eyes Off Of You” and Jennifer Lopez’s “Ain’t It Funny” played.
“Kirsten was smiling and laughing the whole time they danced,” a source tells PEOPLE. “Garrett twirled her around and it was clear they only have eyes for each other.”
