Megan Fox shared several awkward pre-teen photos with fans, featuring her younger self with "citrus" highlights and braces.
"Say hello to my 12-year-old self," Fox wrote in the caption. "I encourage you to admire my citrus/copper colored highlights (thanks Sun-in!) my braces, and my ever present sunburn."
"And yeah I'm brushing my eyebrows with a toothbrush in that one picture," Fox added.
The 26-year-old actress previously posted childhood photos on the social networking site, joking that she looked like "Boardwalk Empire" actor Steve Buscemi.
She also posted four photos of her making various faces in an album titled, "Things You Can't Do With Your Face When You Have Botox," slamming rumors that she had gotten plastic surgery.
Megan Fox and husband Brian Austin Green, 38, are expecting their first child together. The former "Transformers" actress and the "Beverly Hills, 90210" alumni never confirmed the news, but Fox has been photographed with what is now a large baby bump.
The celebrity couple married in June 2010 in Hawaii and had been dating since Fox was 18. She is now 25. Green's son Kassius, whose mother is "General Hospital" star Vanessa Marcil, 43, served as the best man at the wedding and was the only witness.
Fox became an international sex symbol after starring in the first two "Transformer" movies. She recently appeared with Jon Hamm and his real-life partner Jennifer Westfeldt in her indie film "Friends With Kids." Fox played a woman who dates a father but has no interest in becoming a mother.
