Just a day after her hubby Jay-Z performed to a packed arena in DC, Beyonce arrived in DC Saturday to attend the 50th birthday celebration for first lady Michelle Obama. The star studded party took place at The White House and included guest such as Jennifer Hudson, Stevie Wonder family friends, elected officials, entertainers, athletes, business executives and big donors at the gala, which kicked off Saturday and lasted until the wee hours this morning. According to reports the party was spectacular and fun, fun, fun as told by a source to the Tribune:

The first lady “seemed very comfortable and happy. Very celebratory,” said the other source. “It was such a fun, fun party.”

Singer John Legend sang the happy birthday song to Michelle Obama, according to the sources.

They said Beyonce, who is a close friend of the Obamas, sang hits including “Single Ladies (Put a Ring on It)” and “To the Left,” and Wonder gave a more impromptu performance that included “Signed, Sealed, Delivered” and “Do I Do.”

Also on hand were Chicago area friends: Kaye and Wellington Wilson, Marty Nesbitt, Eric Whitaker, Laura Ricketts and Paula and Jim Crown, the sources said.

Before Christmas, invitees got save-the-date notices telling them to come for “Snacks & Sips & Dancing & Dessert.” They were urged to wear comfortable shoes, practice their dance moves and eat before the party, scheduled to begin at 9 p.m. Washington time.

The buffet table offered finger food, including mini sliders featuring beef brisket, the sources said, and an open bar had hard liquor, champagne, beer and wine, the sources said.

Guests were told not to bring cell phones with them, and there was a cell phone check-in area for those who did, the sources said. Signs at the party told guests: No cell phones, no social media.

Bey later shared some more personal photos of she and Blue Ivy touring the White House just hours before the party went down.
