Celebrating a life milestone with her special someone, Sarah Hyland was joined by boyfriend Matt Prokop for a belated 21st birthday bash at The Bank Nightclub inside Bellagio Resort and Casino in Las Vegas, Nevada on Saturday night (December 10).
Tweeting her excitement prior to the Sin City festivities, the Haley Dunphy darling - who turned the big 2-1 back on November 24th - wrote, "Can’t wait to celebrate my 21st with my favorites in Las Vegas at @TheBankLV!!"
Once underway, Miss Hyland was presented with a three-tiered pink cake while spending the entire night alongside her "Geek Charming" beau - whom she recently told Ryan Seacrest in an interview (listen below) that she thinks he's "the one."
As for her hit ABC Comedy, "Modern Family" is currently on holiday hiatus with the next new episode titled "Lifetime Supply" set to air on January 4, 2012.
A synopsis of the installment via the show's website reads: "Phil contemplates the worst, after missing a call from the doctor. Elsewhere, Javier, Manny's biological father, pays another visit to take his son to the horse races , and Mitchell wins an environmental law award, creating a competition."
