Scott Disick and Kourtney Kardashian are officially engaged.

Disick proposed to Kardashian in Paris last week, according to a report.

Laurie Disick, Scott's aunt, reportedly told Star magazine that their family is "thrilled they've finally decided to get engaged." Laurie added that the Disick family are "all so fond of Kourtney, and we wish them a long, happy marriage."

Enstarz reported that Disick was spotted shopping for an engagement ring in Fort Lauderdale, Florida on Oct. 25.

"Scott was most definitely shopping for engagement rings," an eyewitness told Radar Online.  "Scott and his friend looked at a whole selection of amazing rings, all diamond, all different cuts, sizes, settings," the source described of the ring selections at Levinson Jewelers in the downtown area. Adding that he "is taking his time and wants to make the right purchase.

"Scott was in the store for about an hour with a friend," another source told Hollywood Life. "He was looking at expensive watches and there were camera crews filming him.

But when the cameras stopped filming, that's when he looked at rings in private. "He started looking at engagement rings - big diamond ones," the source added. "He was curious. He browsed a few styles."

Kardashian, 33, recently gushed about her relationship with Disick. "We're good right now with how things are," Kardashian told Us Weekly. "We're just trying to figure out our new life with two kids."

Disick proposed after dating Kardashian for 5 years. The couple have two children, Mason, 2 1/2 and Penelope, 3 months.

The next issue of Star magazine that offers details of their engagement arrives on newsstands on Wednesday, Nov. 21.
