Mommy duty awaits! Former child star Gaby Hoffmann is pregnant and expecting her first child with cinematographer boyfriend Chris Dapkins, a source reveals to Us Weekly.

"She and her boyfriend Chris Dapkins are thrilled. Gaby is doing very well," the source tells Us. "She's been staying in L.A. filming another project."

The Girls guest star, 32, revealed a noticeable baby bump while attending the screening of her film Obvious Child in L.A. on June 4. She wore a tight-fitted mustard yellow dress and was photographed beaming from ear-to-ear.

Hoffmann is best-known for her role as Samantha in the 1995 coming-of-age film Now and Then, plus roles in Sleepless in Seattle, and 200 Cigarettes. She most recently played Adam Driver's eccentric sister Caroline on the HBO series Girls. Incidentally, her character revealed she was pregnant (with the child of protagonist Hannah's odd neighbor Laird) on its season 3 finale.
