Ex Bachelorette: Chris Handled Rejection "Like a Man"

He may not have won Ali Fedotowsky's heart on Monday's Bachelorette finale, but runner-up Chris Lambton impressed at least one woman: former Bachelorette DeAnna Pappas.

"Women all over the country are going to be swooning over him! He's a stand up guy, he's good looking and he has a good heart," Pappas -- who split from fiance Jesse Csincsak, whom she found on Season 4, in November 2008 -- tells UsMagazine.com.

"The fact that he cares so much about his mother -- even though she passed away -- that he's so open to talk about her and he gave up his job to go home and help take care of her, that says so much about him as a person," she continues. "He's going to be a wonderful husband, a loving man and he's already a very thoughtful and caring person."

And though Fedotowsky, 25, broke things off with Lambton before their final date when she told him she was in love with Roberto Martinez, Pappas says the 33-year-old landscaper handled the rejection with the "utmost class."

"To be so far into the show and have so many feelings and emotions -- and to have met her family -- I thought he handled it like a man," Pappas, 28, tells Us.

But even though Lambton may have left Bora Bora heartbroken, Pappas says that Fedotowsky's attraction to Martinez, a 26-year-old insurance agent, had been evident since day one.

"It's been clear that her and Roberto have that romantic chemistry that's needed in a  relationship. They really, really like each other," Pappas says. "He's the only guy that she actually looks into his eyes; she actually looks into his eyes when she's kissing him."

So does Pappas have any words of wisdom for the newly engaged couple, who celebrated the show's finale by hitting up a wrap party in Hollywood on Monday night?

"My only advice is to just love each other genuinely, take every day as it comes and really try to get out of Hollywood and settle into normal life," Pappas advises. "I've heard rumors that they've been offered Dancing With The Stars, and my advice is to build the ground before you dive in. It's going to be hard."
