Actress Megan Fox has poked fun at her 12-year-old self by posting childhood photos online.

The Transformers beauty, who is rumored to be pregnant, has previously insisted she hasn't always been known for her looks and she tried to prove her point on Friday (06Jul12) by sharing three pictures from her youth on her Facebook.com page.

Alongside one snap, she writes, "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 has been known to share personal snaps with her devotees - last year (11), she uploaded two images of her as a tot in an album titled, 'I Look Like Steve Buscemi', while she also pulled funny faces to prove she hadn't undergone plastic surgery in another file named, 'Things You Can't Do With Your Face When You Have Botox'.

The actress has yet to comment on reports she is expecting her first child with husband Brian Austin Green, despite showing off what appeared to a 'baby bump' while wearing a bikini as she celebrated her wedding anniversary in Hawaii last month (Jun12).
