Halle Berry walked the red carpet once more with her baby bump this week while on a promotional tour for her new film The Call.

The pregnant 46-year-old actress showed off her growing belly on the red carpet Thursday in Rio de Janeiro, Brazil, for the premiere of her film. She wore a long-sleeved black gown with lace cut-outs, and a photo taken of her from a side angle put her expecting belly in full view.

Thursday's premiere is not the first time Berry has made a public appearance since her pregnancy was announced earlier in April. She attended the premiere of The Call in Argentina on Monday and wore a one-shoulder purple gown that she matched with diamond drop earrings. While posing for photographers she wrapped her arms around her stomach and cradled her baby bump. Click here to see Berry and her baby bump on Monday.

The Call is out in theaters now.

Berry is expecting her second child but her first with fiancé Oliver Martinez. She already has a daughter - Nahla, 5 - from her previous relationship with model Gabriel Aubrey. Berry and Martinez dated for a little over two years and got engaged in 2012.

"I feel fantastic," she told CNN about her pregnancy, adding: "This has been the biggest surprise of my life, to tell you the truth. Thought I was kind of past the point where this could be a reality for me. So it's been a big surprise and the most wonderful for me."

Some were concerned about whether or not Berry's advanced age and diabetes will pose health risks for her and her unborn child. Experts assured those worried that advances in testing and medical care can guard against many medical problems. The baby of an older woman is more likely to have chromosomal changes that can lead to birth defects such as Down syndrome, but experts noted that chances of the above happening are slim.
