'Water For Elephants': Robert Pattinson, Reese Witherspoon Talk Love Scenes, Kissing (VIDEO)

But did he bite?

Reese Witherspoon and "Twilight" star Robert Pattinson feature as a forbidden couple in the upcoming early 20th century circus drama "Water for Elephants," and nothing about the film has gotten more buzz than their supposedly steamy love scenes.

Hope they edit out the giggles, based on what they told Entertainment Tonight.

The pair sat down to talk about filming together -- Reese says she's "lucky" to be able to kiss Rob -- and said it's quite the good time.

"We'll probably just laugh the whole time, because all we do is joke around and laugh... we just have a great time."

There's also a bit of awkward, oedipal chat -- Pattinson played an aged Witherspoon's son in the 2004 film "Vanity Fair," though the scene was eventually cut.
