Makeup free in Maui! The usually made up Aubrey O'Day looked nearly unrecognizable while showing off her fresh face on vacation with her boyfriend in Maui, Hawaii on Tuesday, July 2.

The 29-year-old Danity Kane singer soaked up some sun in a white knit monokini and tiny denim shorts that accentuated her curves. "What's white knit and burnt all over?" O'Day tweeted with a picture of herself. "ME! Maui sun."

O'Day has been flaunting her bikini body in Instagram pictures throughout her romantic getaway. The "Let Me Lay" singer captioned one sexy shot, "Hi my name is Aubrey, and I'm a bikini junkie! Maui babe."

In addition to enjoying the beautiful weather, O'Day has been having fun with local attractions. She and her man posed together for a funny photo with parrots. "Screw Redbull," O'Day captioned the photo. "Maui gives you wings!"

The couple also took advantage of the cuisine. "Don't threaten my man and me with a buffet," O'Day tweeted with a picture of table covered with food. "More please. Maui."

Unfortunately, her tropical vacation came to an end on Tuesday and she's now getting back to work on her solo album. "Last day in paradise," she tweeted. "Then back on that Between Two Evils grind."
