JWoww is getting ready to fist-pump her way down the aisle!

MTV's Jersey Shore and Snooki & JWoww star (real name: Jenni Farley) accepted boyfriend Roger Mathews' proposal - and a dazzling pink and white engagement ring.

Together for two-and-a-half years, JWoww, 26, and Mathews, 37, got engaged during a high-flying skydiving session when Mathews presented his girlfriend with a ring that totaled 5 carats and features 2.5 carats in diamonds surrounding the center stone. (WetPaint broke news of the engagement last week.)

"Thank you everyone on the engagement wishes," the reality star tweeted Wednesday.

As news of her impending nuptials spread, JWoww's fellow MTV costars were quick to offer her and Mathews their best wishes. "CONGRATS on the engagement boo! Love you so much" Snooki (real name: Nicole Polizzi) -- who announced her engagement to Jionni LaValle in March and welcomed son Lorenzo in August -- tweeted.

"I just heard the news! They grow up so fast," mused Pauly D on Twitter. Added the Jersey Shore star: "It's official: I'm the only single one left . . . now accepting applications #SeriousInquiresOnly."
