Pete Wentz Dyes Hair Blonde: Fall Out Boy Rocker Shows Off New Do on Instagram

They say blondes have more fun, and it looks like Pete Wentz is out to see if there is any truth behind the saying.

The Fall Out Boy bassist showed off his new do on Instagram on Monday, Aug. 18. Not only was his hair blonde -- and platinum blonde at that -- but it was trimmed edgy and short, as well.

"Prepared for new art on the horizon," he captioned the Instagram pic. Looks like Fall Out Boy fans could expect some new tunes in the near future, or at least that is what the cryptic message seems to imply.

The 35-year-old's hair transformation comes at a pivotal time in his life. He and model girlfriend Meagan Camper announced in February that they were expecting their first child together. Camper posted an Instagram photo in June of her growing baby bump, and she is simply glowing!

This will be the second child for Wentz, who is also the father of 5-year-old Bronx (from his previous relationship with Ashlee Simpson).

Simpson and Wentz got married in 2008 and welcomed son Bronx later that year. In 2011, Simpson filed for divorce, citing "irreconcilable differences." At the time, a source claimed Wentz did not want to part ways with his singer wife.

Could Wentz's new hair be a harbinger of new and exciting things in his life? A new album, or even just his adorably growing family?

Or could this just be the first step towards the singer's mid-life crisis? Either way, his blonde locks are a good look, and have earned the public's seal of approval.
