Pamela Anderson Ditches Blond Locks For Brunette Hair (PHOTO)

Pamela Anderson has firmly left her "Baywatch" days behind her.

The Canadian babe ditched her iconic blond locks for a brunette hairdo, which she was seen trying to cover up under a fedora while walking through the Los Angeles airport over the weekend.

Pammy has gone through a few hairstyle changes in the past few weeks. The "Barb Wire" star debuted an adorable pixie cut last month when she walked the red carpet with ex-husband Rick Salomon, which inevitably led us to compare her new 'do to Jennifer Lawrence's pixie cut. (We prefer Pam's.)

While we don't know what made Tommy Lee's ex go brunette, she did explain to Ellen DeGeneres why she shed most of her hair.

"I just thought my hair had had a ‘life,;" she told the talk show host of her decision to chop her hair off. "And I wanted to put that behind me and start fresh, and I thought it would be good for the marathon. And it was!"

The marathon that Pam was referring to was the New York City Marathon which the 46-year-old ran a few weeks ago to raise funds for a Haiti charity.

Looking good, Pam!
