PHOTOS: LeAnn Rimes -- Curveless In Cabo

Newlywed LeAnn Rimes showed off her skinny frame as she enjoyed her belated honeymoon with new hubby Eddie Cibrian in Cabo San Lucas, Mexico on Thursday.

Rimes, 28, wore a white jumper and short shorts that showed off her thin arms and legs, and protruding collarbone.  Despite getting a lot of flak over her frame, Rimes has repeatedly denied having an eating disorder.

As for Cibrian, 37, the hunky actor wore a white hat, black shirt and red board shorts, while walking hand-in-hand with his songbird wife.

Among their activities, the pair took a ride at sea.

“Wow, Eddie surprised me w/ a day on a gorgeous yacht!!!!! It's a stunning day!”  Rimes tweeted.

Rimes and Cibrian have been tabloid mainstays since their love affair began in 2009, when both were married to others. (Cibrian to his wife of eight years, Brandi Glanville, and Rimes to her husband of seven years, Dean Sheremet.)

The couple married last month.
