‘Sin City 2’ Cast Jessica Alba Smolders In Bikini On Her Birthday Celebration; Hits Vegas For Some ‘Me Time” With Husband Cash Warren

"Sin City" cast Jessica Alba not only smoldered in a printed bikini for a belated birthday celebration with friends in Las Vegas over the weekend but also managed to fit have"me time" with husband Cash Warren. The couple, however, made sure to go home early to be with their daughters in time for Mother's Day.

"Sin City" cast Jessica Alba, who turned 33 on April 28, was named by The Helping Hand of Los Angeles "Mother of the Year" during a luncheon in Beverly Hills on Friday. She and her husband then hit Las Vegas after the event along with some friends.

That same night, the couple celebrated another milestone in Jessica Alba's life as they partied at the Hakkasan Restaurant & Nightclub in MGM Grand with bestfriend Kelly Swayer, childhood friend Lauren Andersen, cast members of "The Veil", Katherine Power (founder of Who What Wear), and hairstylist Jen Atkin, the Las Vegas Sun reported.

They rented out the dining room at the second level for some bit of privacy while "Sin City" cast Jessica Alba's guests enjoyed "gluten-free" food and cocktails, the publication added.

On Saturday, the group washed off the hangover by taking a dip at the Wet Republic Ultra Pool in the same hotel, said Yahoo! Celebrity. Jessica Alba wore an animal print-bikini and showed off her post-baby sexy body while sharing a laugh with her close friends.

Then on Sunday, she arrived home just in time to celebrate Mother's Day with her two daughters, Haven and Honor, as well as her own mom, Cathy Alba.

During her birthday, husband Cash Warren uploaded a family photo in social media along with the caption: "Happy Birthday to my one and only. Thank you for being a constant reminder for what's important in life...family & friendship. I love you more than my words can ever express."
