Jessica Simpson shared a snap of herself in Hawaii today. She showed off her growing baby bump in a bikini during her getaway with family and friends. Jessica confirmed her second pregnancy earlier this month with a cute picture of daughter Maxwell next to the writing, "big sis." Jessica, Maxwell, and Eric Johnson have been relaxing with Jessica's sister Ashlee and her son Bronx as well as their mom Tina and pals CaCee Cobb and Donald Faison. CaCee and Donald joined in on the trip after getting married in LA on Dec. 15. They hit the beach to soak up the sun yesterday splashing around with a bikini-clad Ashlee and Bronx. The group took a break from the sand today though, to watch the Dallas Cowboys game, though the Texas team's season is now over following their loss to the Washington Redskins.

A bikini-clad Ashlee Simpson joined newlyweds Donald Faison and CaCee Cobb for a day at the beach yesterday in Oahu, Hawaii. Ashlee's mother, Tina Simpson, and her son, Bronx, were also along for the fun. Ashlee and CaCee splashed around with Bronx in the waves, and Donald did a little bodysurfing, before the group took a break to relax on the warm sand.

CaCee and Donald got married earlier this month. Jessica Simpson served as a bridesmaid at the nuptials and also vacationed with the group in Hawaii this week, though she wasn't with them by the shore yesterday. Jessica's been tweeting family photos during the getaway, including one that seemed to confirm that she is pregnant for a second time. The picture, snapped on Christmas Day, showed her daughter Maxwell sitting in front of the words "Big Sis" written in the sand.

Jennifer Aniston had a few companions for her latest afternoon in the Cabo sun on Friday. She was joined by a bikini-clad Emily Blunt and pal Molly McNearney, who is Jimmy Kimmel's fiancée, and John Krasinski. Jennifer's own fiancé, Justin Theroux, was once again shirtless to soak up rays and show love to Jennifer, who sported a bright red top. The other couples landed in Mexico on Thursday to join in on Jennifer and Justin's getaway. The vacation is just one of many highlights from Jennifer and Justin's big year, including their Summer engagement and European travels.

Yesterday, the group was back out tanning and exploring the beach. Jimmy, John, and Molly tried their hand at stand-up paddleboarding, while Justin and Jennifer, in a brown bikini, lounged in the sun.
