Sofia Vergara enjoys surprising her fans with different looks. Recently, she turned herself into a blonde bombshell after the Modern Family star becoming famous as a brunette.

Now, she is shocking her millions of fans with a racy pose in a thong bikini.

The former brunette Vergara dyed her hair blonde for summertime. Gone was her dark mane and in its place was a layered, lightened style with bright highlights and warm honey lowlights, according to EOnline.

This isn't the first time the actress has rocked a flaxen hue. In fact, Vergara is a natural blonde, says she.

"When I started acting, I would go to auditions and they didn't know where to put me because I was voluptuous and had the accent - but I had blonde hair," the actress told Self magazine in 2010. "It was ignorance: They thought every Latin person looks like Salma Hayek. The moment I dyed my hair dark, it was, 'Oh, she's the hot Latin girl.' I loved it. I'd always felt a little 'too much' as a blonde, like a big-mouth version of Pamela Anderson. Being brunette toned me down a bit."

Now, the sexy actress is showing off her famous curves.

On Saturday, the Modern Family star posted a revealing WhoSay picture showing off her shapely behind lounging by the pool. In the smiling selfie, the 40-year-old beauty wears a pink thong bikini bottom-and not much else. Sounds like Sofia's team was trying to track her down, so she coyly captioned the shot, "Where @keegankillian and @luisbalaguer [her manager] cant find me!!!"

Obviously, Sofia is now proud of her womanly assets now (and the rest of the world is, um, obsessed, too) but there was a time she didn't love being a well-endowed woman.

"I was still skinny but suddenly I had these big boobs," she told Shape magazine, about developing her ample chest during puberty. "It was terrible! I used to tell my mother, 'I'm going to cut these off as soon as I turn 18.'"

Earlier this month, Vergara told The Huffington Post that she owed a lot to her curves

"To be a pretty girl, to be a voluptuous girl, has opened many doors for me. I would be ungrateful to say it's all because of my brains and my talent," the actress said.

But she continued, "I have stayed working for 20-something years, so there must be something else behind the guns."
