Ashlee Simpson lounged poolside while on vacation in Cabo San Lucas, Mexico, over the weekend.
The 28-year-old single mom hid her face under a big hat and sunglasses, but made sure to flaunt her bikini body in multicolored two-piece and sheer cover-up. Simpson was sipping on cocktails with friends as she worked on her tan.
Her sister, Jessica Simpson, is due to give birth any day now, so now's the time for Ashlee to get in some R&R.
