Halle Berry has been revealing the slightest peaks of her growing baby bump since announcing her pregnancy weeks ago.

The actress was spotted walking though LAX airport in Los Angeles on Thursday with her pregnant stomach on full display. The X-Men star was dressed in a gray sweater, showing off her bump, wore dark brown sunglasses and a hat that covered her brown hair.

Berry arrived in Los Angeles after spending some time in Montreal, Canada filming her latest X-Men film, Days of Future Past. 

The film's director, Brian Singer, tweeted on April 22 a photo of Berry in her X-Men costume. Her baby bump was barely showing and he captioned the image, "Storm watch #HalleBerry #XMen #DaysOfFuturePast."

X-Men: Days of Future Past follows 2006's X-Men: The Last Stand and 2011's X-Men: First Class. The movie is set to arrive in theaters on July 18, 2014. 

The 46-year-old has been candid about her second pregnancy, which is also her first with fiance Oliver Martinez. She revealed that getting pregnant for the second time was one of the biggest surprises of her life, and admitted that she mistook her pregnancy for kidney stones. 

"I was at the doctor's when they told me and I was completely shocked... I didn't see it coming. I went to the doctor because I thought I had kidney stones or something. So it was a massive surprise," she said.

The actress said she is very happy to be expecting her second child.

"I feel fantastic," she told CNN. "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."

Even her 5-year-old daughter, Nahla, is excited to have a little sister or brother. Berry said about her daughter, "Not long ago she asked G-d for a little sister, but I tried not to get her hopes up." 

"At 46, I didn't know if I'd be able to get pregnant again. Olivier and I have always wanted to be parents," she added.
