Our little Haley Dunphy grows up.

Sarah Hyland who plays (Haley Dunphy) the teenage daughter of Phil Dunphy on the ABC hit comedy Modern Family celebrated her belated 21 birthday this week end. The Modern family starlett held a lavish party at the The Bank Night Club inside the famed Bellagio Resort and Casino in Las Vegas. Her birthday was actually on Nov 24 but because of work and other engagements this was the earliest she had time off to celebrate. She was joined by her boyfriend Matt Prokop. Ahh….It seems like it was only last Wednesday when she was a young 15 year high school student and look at her now all grown up.
