Beyonce, Jay Z lead celebrity guest list for President Obama's 55th birthday bash

The stars lined up and got in "Formation" for President Barack Obama's 55th birthday party, held at the White House on Friday night.

First Lady Michelle Obama made sure her husband spent his last birthday as President in style, hosting an epic party that included the likes of Beyonce, Jay Z, Kendrick Lamar, Stevie Wonder, and John Legend.

Usher, Sarah Jessica Parker, Jennifer Hudson, Alonzo Mourning and Hillary Clinton were also said to be in attendance.

And while for the most part the event remained private and exclusive, a few celebs just couldn't contain their excitement.

"@thecookiej and I getting ready to go to President Obama's birthday party!" Magic Johnson captioned a photo before heading out for the soiree.

And before we knew it, stars flocked to the party left and right. George Lucas, Ellen DeGeneres (accompanied by wife Portia De Rossi), and Robin Roberts were just a few caught by fans on their way into the celebration.

Some were able to contain their excitement until after the event ended.

"An honor to attend President @BarackObama 55th birthday celebration at @WhiteHouse tonight," Al Roker posted to Twitter, along with a photo of himself and wife Deborah Roberts.

"Leaving the White House after the celebration of President Obama's birthday. His last birthday as President," Reverend Al Sharton wrote.

Tonight was a night I will never forget. #BarackObama #happybirthday," Nick Jonas -- taking a break from his tour with Demi Lovato -- simply stated after the party.

Also at the affair was Vice President Joe Biden, who earlier in the day presented the commander in chief with one special birthday present.
