Pamela Anderson

Pamela Anderson is back in her natural habitat: running on the beach in her red Baywatch bathing suit.

Sadly, this doesn't mean the lifeguard drama isn't being rebooted. People reports that the actress donned the sexy swimwear for a commercial she's shooting in Rio de Janeiro.

Dancing with the Stars all-stars: Grading the new pairs

Anderson first rocked the one-piece while playing C.J. Parker on Baywatch from 1992-1997.

This fall is a very nostalgic time for the actress. In addition to returning to her Baywatch roots for the commercial, Anderson will also be returning to Dancing with the Stars this fall for the upcoming all-star season. Starting Sept. 24, she and Tristan MacManus will vie for the mirror ball trophy once again. Anderson first appeared on the reality competition's 10th season in 2010.
