Inside Carrie Underwood's tropical honeymoon

The "American Idol" winner has been living it up in Tahiti, alternately relaxing in the water but also seeking out what the French Polynesian island has to offer.

"Carrie and Mike have enjoyed swimming and snorkeling with reef sharks," a source tells People. "They also toured the island via helicopter."

Taking to the sea and air can be hard work though, so the newlyweds have also been kicking back on their private deck and chilling on the beach, which gives Underwood another chance to show off another bikini.
