Kirsten Dunst and Garrett Hedlund "only had eyes" for each other during a recent night out.

The Hollywood couple helped a pal celebrate their birthday at Bootsy Bellows in West Hollywood. They were seen laughing and joking, as well as showing off their dance moves to tracks by Lauryn Hill and Jennifer Lopez.

"Kirsten was smiling and laughing the whole time they danced," an insider told People. "Garrett twirled her around and it was clear they only have eyes for each other."

Kirsten got to the venue at around 10pm and opted to show off her trim figure in a black dress and matching high heels.

Although she didn't walk in with Garrett, the pair soon met up. He dressed down in a simple T-shirt and jeans combination.

The two stars seemed relaxed and happy, spending most of the evening talking together and swapping kisses.

Kirsten, 30, and 27-year-old Garrett began dating last year.
