Bruce Willis on Life After Having His Fifth Daughter

ET's Brooke Anderson co-hosted the Entertainment Industry Foundation's 2014 Revlon Run/Walk for Women at the Los Angeles Memorial Coliseum Saturday, where she caught up with Bruce Willis, whose wife Emma just gave birth to his fifth daughter Evelyn Penn Willis on May 5!

Willis shared that both he and Emma are doing "great," though the 59-year-old Die Hard star did admit to being a bit tired.

"I kinda rest once in a while," he joked.

As for why the Revlon Run/Walk for Women -- which has already raised $70 million for cancer research, treatment, counseling and outreach programs -- is so important to him, the answer is obvious.

"I'm a big fan of women -- I'm surrounded by women," he smiled.
