Elisha Cuthbert: Engaged to Dion Phaneuf!

Elisha Cuthbert already knows a thing about Happy Endings quotes. Now she's even more well-versed on the subject in real life as well as TV.

The actress is engaged to Dion Phaneuf of the Toronto Maple Leafs!

Cuthbert, 29, announced on Twitter that she's "Happily, happily, happily, happily engaged! This has been the most amazing weekend ever."

The couple, who began dating way back in May 2008, celebrated at New Glasgow Lobster in Prince Edward Island, Canada, last night.

"Last night we had the privilege of hosting a surprise engagement party for Dion Phaneuf and Elisha Cuthbert," the restaurant tweeted.

"Congrats to them both."

Announcing their engagement at the PEI venue was "a nice surprise for all their guests ... Congrats to them both and LOVE the ring!"

Phaneuf, 27, "never said it was for an engagement party," a source says. "They invited 40 friends and family to celebrate at the restaurant."

"Elisha looked very happy and pleased. She was showing off her ring to her family and the wait staff," the source at the restaurant adds.

"Dion and Elisha both got up an gave a speech and thanked everyone for being there and celebrating this exciting time with them."

Cuthbert previously dated NHL player Sean Avery, who was suspended for saying Phaneuf was enjoying his sloppy seconds in 2008.

Congratulations to Elisha and Dion!
