Jessica Alba: 'Keep Your Man on His Toes!'

New mom Jessica Alba says the secret to a successful marriage is to keep your man on his toes.

The 'Sin City' actress -- who married partner Cash Warren in a secret ceremony on May 19 -- says the most stable relationships are the ones where the woman is feisty and strong-minded.

She reveals, "Some men don't like their women to speak up, some like their women to wait on them hand and foot and put the dinner on the table, be submissive and never talk.

"But then there are men who want feisty, crazy women who are going to tell them how they feel every day and keep them on their toes. Most people just marry the wrong person and when you don't marry the right person how can you possibly expect to be together forever?"

Jessica -- who gave birth to the couple's first daughter, Honor Marie, on June 7 -- recently revealed that she and Cash were "glued" to the 2008 Beijing Olympics.

She wrote on the My Space Celebrity blog, "I don't know about you all but Cash and I have been glued to the Olympics. How amazing was the opening ceremony?!?

"I still don't know how they coordinated 2008 people to move in perfect sync. The men's 400M relay was insane. We were down by almost a half body length going into the final turn and then next thing you knew it was closer, closer, closer until we touched the wall first!

"Cash and I went crazy. The shot of Michael Phelps after the race ended cheering with his teammates is so memorable. The last time I got this excited watching sports was when Baron was in the NBA playoffs. Next year we get to watch him in Los Angeles. Go Clippers!!"
