Heidi Klum was in search of something blue during her wedding festivities, but unfortunately it cost her big time.
The former "America's Got Talent" host has been in Capri, Italy with new husband Tom Kaulitz after tying the knot last weekend in front of family and friends.
After the ceremony, Mr. and Mrs. Kaulitz were reportedly joined by their wedding party for a venture in the famous Blue Grotto, where swimming is strictly forbidden.
RTL news in Germany reports that they did in fact enter the water, and after police found out about the swim, the couple was fined around 6,000 euros ... or about $6,700.
It's not the first time Klum and Kaulitz have taken an illegal dip in the Blue Grotto, as they shared a romantic swim back in October. It's unclear if they were hit with a fine that time.
The Blue Grotto is only about 200 ft long and 80 ft wide, and must be entered by lying down on a boat and using a guiding chain, attached to the walls of the cave, to enter.
The grotto is one of several magnificent sea caves around the world that is highlighted by a brilliant blue light.
Officials also say swimming is illegal because, "high waves can slam swimmers against the stone of the low cave mouth."
Klum has not yet commented on the fine, but she's still probably recovering from the whirlwind wedding just days earlier.
The supermodel wed the "Tokio Hotel" guitarist aboard the "Christina O" yacht, however they had already legally married back in February during a low-key ceremony in L.A.
