Taylor Swift Celebrates 25th Birthday With Beyoncé, Jay Z, Justin Timberlake & Sam Smith

It's been fun a week for our favorite country pop star Taylor Swift. Her Victoria's Secret Fashion Show performance aired, she tore down the stage at the Z100 Jingle Ball, she received the "Woman of the Year" honor from Billboard, and celebrated her 25th birthday with some of the biggest names in music.

Swift hosted a pizza party Friday night at her Tribeca apartment after performing in front of 18,000 fans at New York City's Madison Square Garden. You would have thought the party was a pre-Grammy soiree from the list of big name music acts in attendance. Beyoncé, Jay Z, Justin Timberlake, Sam Smith, Selena Gomez, Charlie XCX, and Nick Jonas were just a few stars who came to celebrate Swift's born day, posing for the ultimate group photo. Swift would later post the pic on Instagram with the caption, "So this is being 25….. #WHAT #bestbirthdayEVE."

To top off her birthday celebration, Aretha Franklin presented Swift with a cake while singing "Happy Birthday." Not a bad way to grow older.
