We’re officially on Halle Berry bump watch. Less than two months after the actress first announced her pregnancy, Berry and her bump were spotted out in Sherman Oaks, Calif., running errands Tuesday. The 46-year-old star was seen sporting a strapless, tight black dress, accentuating her now-four-months-pregnant figure.

Earlier this month, Berry was seen working out in Beverly Hills in similar tight-fitting attire with a noticeably smaller bump. The baby, due on an unidentified date this fall, will be the first child for Berry’s beau of more than three years, 47-year-old actor Olivier Martinez. Berry has a 5-year-old daughter, Nahla Aubry, with her former flame, model Gabriel Aubry.

The couple is rumored to be expecting a boy, according to US Weekly. TMZ reported in April that according to celebrity lawyer Steve Kolodny, rumors that the engaged couple is currently in a legal feud over child support agreements are false, claiming the famous duo have yet to settle on any paternity agreements.

The “Monster Ball” actress commented on her highly publicized pregnancy, calling her baby to be a blessing at the 20th Annual Entertainment Industry Foundation/Revlon Run/Walk on May 12 in support of Breast Cancer research, a cause close to the actress’s heart.

“I’m thinking that this is a miracle. I feel really happy,” Berry told Entertainment Tonight. “It’s one of the best things that's happened in my life, for sure.”
