Nick Jonas: "He's Very Mature for His Age," Says Sexy Co-Star Isabel Lucas

The two play lovers in upcoming thriller Careful What You Wish For

Nick Jonas was only 20 years old when he shot his upcoming drama, Careful What You Wish For.

Isabel Lucas, 29, who plays the married woman that Jonas has an affair with, was very impressed.

"He's lovely," the sexy Aussie told me at the MOCA 35th Anniversary Gala Presented by Louis Vuitton. "He's very mature for his age. I think he was very focused on doing a really good job and rising to the occasion."

In a teaser clip for the film, Lucas stuns in a white bikini while a shirtless Jonas shows off his ripped bod while climbing out of a lake.

Also coming up for Lucas is The Water Diviner, a drama directed by and starring fellow Aussie Russell Crowe.

"He was just very warm and very specific and clear about what he wanted and every empathetic as a director because he's an actor himself," Lucas said, adding that she "relished" and "was very grateful" for the experience.
