“Extra’s” resident bad boy Steve Santagati chatted with actress Reese Witherspoon about her new romantic comedy “How Do You Know,” and got Reese to open up about some of her worst dating experiences.

Reese co-stars in the film with Owen Wilson, and said that she dated a guy similar to Wilson’s character — the type of player who has a bathroom drawer full of toothbrushes.

“I have seen the toothbrush drawer,” Witherspoon told Steve about spending the night at an unnamed ex’s home. “I woke up with the toothbrushes and it was horrifying.”

That’s not the worst of the actress’ dating nightmares. Reese said she once “had an experience where I opened up the closet looking for a washing machine or something, and it was like a line of bikinis… different sizes of bikinis with the tags on them. I was like ‘Oh God’.”

Witherspoon has dated her share of A-list men, including “Love & Other Drugs” star Jake Gyllenhaal, but the 34-year-old star has moved on — and into the arms of Hollywood agent Jim Toth.

When asked if she would recommend other stars to avoid dating a fellow thespian, Reese replied, “I have a whole list of things I’d recommend. I could give a seminar.”

Catch Reese in “How Do You Know,” and we know it opens December 17.

Actress marvels at the ‘fervor’ around her ‘Water for Elephants’ co-star.

Reese Witherspoon became a household name in the late ’90s with a string of scene-stealing turns in films like “Pleasantville” and “Election.” Around the same time, Leonardo DiCaprio was transforming from teen heartthrob to mature Hollywood A-lister, thanks to the nearly $2 billion success of “Titanic.”

Over a decade later, Witherspoon has been thinking back to that pop culture period. It’s the only way she can make sense of the overwhelming popularity of her “Water for Elephants” co-star Robert Pattinson.

“The only thing I can compare it to is when Leo was in ‘Titanic,’ ” she told MTV News while promoting her upcoming movie “How Do You Know.” “It was that kind of fervor about a person. The women lining up outside the set — it was just unbelievable — till 5 o’clock in the morning waiting to just glimpse him.”

The Tennessee set of “Water for Elephants” was basically no different than what happens when the “Twilight” vamp goes anywhere. As director Francis Lawrence told us in the fall, “[E]very day there would be, like, 50 people [staked out] … . [T]here would be people camped out in the hallways of our hotel. All day, all night long, it didn’t matter. People were there to try to catch a glimpse.”

Witherspoon, of course, got an up-close-and-personal glimpse of RPattz, and she was happy to report back to us: “He is extraordinarily attractive. I’m not gonna lie,” she said.

“Robert is such a great guy from a great family,” she explained. “That’s the thing that’s so funny. He’s not really this bad boy; he’s just a great guy and really worked hard on ‘Water for Elephants.’ He really worked long hours, long days. He looks totally different in the movie.”
