Rumours have been making rounds about how the New Jersey girl happened to date one of the most loved youngsters in America, the New York Daily News reports.
Some websites have claimed that the Jonas Brothers member grew up next door to her in Wyckoff, New Jersey.
However, as per People magazine report, the couple met about two years ago in 2007 while both of their families was on vacation in the Bahamas.
In fact, it was Kevin who chased the girl- next-door.
Deleasa, said of their initial encounter: “I didn’t know who the Jonas Brothers were.”
The first photos of the couple together surfaced in October 2008, when the two were spotted smooching and snapping photos of each other during a stroll through Point Mugu, California.
Again earlier this year in March, they were found kissing in the front seat of Jonas’ SUV while driving around Beverly Hills.
They then shopped for engagement rings in some of the most expensive jewellery stores, according to reports of JustJared.com.
The celebrity had proposed Deleasa for marriage presenting a cushion-cut diamond ring he designed himself with Jacob & Co.
