Serena Williams, who won her fifth Wimbledon crown Saturday, will be one of the first guests on tonight's new improvisation series -- "Trust Us With Your Life" -- at 9 p.m. ET on ABC.

From the creators of "Whose Line Is It Anyway?", the show is hosted by Fred Willard ("Best in Show") and will feature celebrities such as Williams, David Hasselhoff, Ricky Gervais, Jerry Springer and Mark Cuban.

The format finds each celebrity reminiscing about key episodes in their lives, then improvises in acting out those moments. Wayne Brady, Colin Mochrie, Jonathan Mangum and Greg Proops will be some of the regulars improvising.

"Serena is an amazing goddess who plays tennis like a beast," said Brady, who hosts "Let's Make a Deal" and is working on a new R&B album. "She was stunning on the show and a great sport. And everyone gets to learn a little about her life."
