Ashlee Simpson -- And Her Bikini -- Heat up Hawaii (PHOTOS)
Ashlee Simpson is making some waves of her own.
After a week that saw her big sister Jessica grabbing headlines -- she officially announced her pregnancy on Christmas Day after Celebuzz first confirmed the newson Dec. 19 -- Ashlee got some well-deserved attention the good old-fashioned way: she donned an itsy-bitsy, teeny-weeny bikini.
The 28-year-old wore the black-and-white swimsuit Saturday as she frolicked with her son Bronx, 4, in Oahu, Hawaii. Also on hand: Jessica's BFF CaCee Cobb and her new husband, Scrubs star Donald Faison. The two wed earlier this month in L.A. in front of celebs like Zach Braff, Seth Green, Sarah Chalke -- and, of course, the Simpsons (Jess served as maid of honor).
Ashlee was previously married to Fallout Boy bassist Pete Wentz -- Bronx's dad -- from 2008 to 2011.
Who do you think Ashlee should date next? Should she stick with Hollywood hotties or try an everyday guy? Let us know in the comments section.
