She may be a drop-dead gorgeous Victoria's Secret Angel set to wed on-again boyfriend Adam Levine, but Behati Prinsloo is just like any other newly engaged lady: She's excited to show off her new rock! On the evening of Wednesday, July 17, 24 hours after the Maroon 5 singer and Namibian supermodel confirmed -- to much surprise -- that they'd reconciled and gotten engaged, Prinsloo, 24, was in a festive mood  at Mercer Kitchen in NYC's Soho nabe.

In grainy shots from Prinsloo's night out, she gabbed excited with a male and female friend; smoking a cigarette, the blonde proudly stretched out her left hand to give her pals a better look at the sizable diamond ring from the Voice coach, 34.

The sexy couple's engagement plans seemed to come completely out of the blue. Dating for about a year, they'd quietly split this past spring, with Levine rebounding with Sports Illustrated model Nina Agdal.

"After Adam broke up with Behati, he couldn't stop thinking about her," one source explained. "He realized he really loved her and wanted to be with her."

After ending his fling with Agdal, 21, Levine (who has dated another Victoria's Secret stunner, Anne V) recently reunited with Behati and proposed this past weekend.

"Behati is thrilled!" another insider says. "She knew that they were meant to be together."
