Heidi Klum posts vacation photos of her sunburned behind, cornrows

Heidi Klum spent Fourth of July weekend in the Bahamas with her bodyguard boyfriend, Martin Kristen, and four children, according to the New York Daily News. But even perfect beach vacations can have their mishaps.

The 5-foot-9 mom, model and television personality shared a risque Instagram photo of her burned butt cleavage over the weekend. "Ouch!" the 40-year-old captioned the image.

The 40-year-old German native also tried out a new hairstyle -- a sleek set of cornrows.
