Mila Kunis & Ashton KutcherThey’re one of the cutest couples in Tinseltown, and Mila Kunis and Ashton Kutcher looked adorable as they attended Kunis’ brother’s wedding in St. Petersburg, Florida on Saturday (December 7).

The “Oz: The Great and Powerful” babe and her “Jobs” hunk got all gussied up and headed over to the Cathedral Church of Saint Peter where Michael Kunis said “I Do” with his lovely bride Alexandra Blacker.

And though Mila and Ashton still haven’t taken the plunge themselves, they certainly looked fabulous in their wedding gear.

One eyewitness told press, “Mila wore a gold band on her engagement ring finger but it didn’t have a diamond, just a simple gold band similar to a wedding band. She was very happy for her brother and his wife. During the ceremony, she stood at the altar and seemed very focused on the vows.”
