"I am so lucky," Witherspoon gushes to Entertainment Tonight of her love scenes with Robert Pattinson in their upcoming movie Water for Elephants. "He's so amazing and wonderful and sweet and just the nicest guy too, so you can just add that to the soup."
"I mean, he's just so good looking and he's a really nice person," she continues.
That said, Witherspoon admitted the pair have a more humorous than amorous relationship off screen. "We'll probably just laugh the whole time, because all we do is just laugh and joke around," Reese says.
In Water for Elephants, which arrives in theaters on April 22, Witherspoon, 34, and Pattinson, 24, play lovers involved in a triangle that develops between their characters and Witherspoon's onscreen husband.
And this is not the first film they've been in together: Pattinson had a part as Witherspoon's son in Vanity Fair – only it ended up on the cutting room floor. Still, Withersoon has some vivid memories of first seeing the actor.
"He was walking down this corridor and I turned to the director and I said, 'That's my son? He's so good looking,' " she says. "I was like, 'He's so hot!' "
In real life, Witherspoon is engaged to talent agent Jim Toth, 40, and Pattinson continues a low-key romance with his Twilight costar Kristen Stewart.
