PDA Alert!

Lena Dunham was caught in a steamy embrace with her rocker boyfriend, Jack Antonoff, in Hollywood, Calif., yesterday (Dec. 9). The "Girls" star, 26, was seen cuddling and making out with the Fun. guitarist, 28, outside of Kings Road Cafe after the pair enjoyed lunch.

Hey, girls just wants to have fun.

Dunham and Antonoff, whose band just received six Grammy nominations including Record of the Year and Best New Artist, began dating in September, according to Us Weekly.

"Lena's crazy about the band," a pal tells Us Weekly, with another source adding Dunham "has asked to use Fun. songs on 'Girls.'"

And despite their hectic schedules, "they have a good time when they can get together," an insider says.
