On camera, the love scenes between Reese Witherspoon and Robert Pattinson in their period drama "Water for Elephants" — which opens in theaters Friday (April 22) — look glamorous and romantic. Behind the scenes, however, it was anything but.

Never mind that both stars were involved in relationships during the filming of the big-screen adaptation (Witherspoon with her now-husband, Jim Toth, and Pattinson with speculated girlfriend Kristen Stewart) but the 24-year-old actor also happened to be fighting a nasty cold.

As the "Twilight" hunk revealed during his "MTV First: Robert Pattinson" special, "The love scene in ['Water for Elephants']: I was doing it when I had a really bad cold." He went on to divulge, "My nose is running all over the place, and it was in one of the additional photography scenes, and Reese had this wig on, and literally, I was wiping my nose on her wig."

And when his Oscar-winning co-star sat down with us, she confirmed it was just as unsavory as he described. "He did have a very runny nose, yeah," she recalled, adding, "It wasn't appealing; it wasn't pleasant."

Still, the 35-year-old actress knows that even a runny nose wouldn't deter Pattinson's most fervent fans. Her advice for anyone planning on getting close to RPattz on or off camera: "Bring a Sudafed!"

However, when Witherspoon isn't dispensing advice on how to get through a love scene with RPattz, she's enjoying domestic bliss with her husband. In fact, the newlyweds have been finding themselves in the same situation as many couples: compromising what shows to watch on television.

The actress said that while she's had to watch the biker drama series "Sons of Anarchy" against her will, she's now turned into "a big fan." But, there was no need to convince the star to watch "Eastbound and Down," the soon-to-be-retired HBO comedy starring Danny McBride.

" 'Eastbound and Down' makes me laugh," Witherspoon told MTV News. "You gotta love Kenny Powers."
