(CBS) First lady Michelle Obama celebrated her 48th birthday on Tuesday night at BLT Steak near downtown D.C., just a few blocks from the White House.

The first lady and President Barack Obama had a long dinner in a private room with several friends and colleagues, including White House senior advisor Valerie Jarrett and Attorney General Eric Holder, reports the Washington Post.

The president even chatted with some fellow diners on his way back from the men's room, the Post reports. While they were out celebrating, a smoke bomb was tossed over the fence and onto the lawn outside the White House during an Occupy protest. The first couple  returned while authorities were investigating the incident.

Earlier in the day, the St. Louis Cardinals visited the White House to celebrate its World Series win. The team presented the Obamas with jerseys and World Series bats.

"When we first married, it was a little controversial that she was 20 years younger than me, but now it seems to have worked out OK," the president, 50, joked on Tuesday, according to the Associated Press.
