Barack Obama has officially kicked off his duties for a second term as the 44th President of the United States.

On Sunday, the 51-year-old was joined by his family — wife Michelle Obama (who was sporting new bangs) and their daughters Sasha and Malia — for the private swearing in, administered by Supreme Court Justice John Roberts.

Vice President Joe Biden was sworn in by Supreme Court Justice Sonia Sotomayor hours earlier at the Naval Observatory.

The formal gathering, which satisfied the Constitutional requirement that the swearing-in is held on Jan. 20 after every election, was a far cry from Monday’s highly anticipated public affair.

Some 800,000 people are expected to descend upon the National Mall on Monday for the president’s star-studded inauguration ceremony. Four years ago, an estimated 1.8 million people attended the president’s historic swearing-in.

As previously announced, Beyonce, Kelly Clarkson and James Taylorare all slated to perform for the president.

On Saturday, Katy Perry, Usher, Nick Cannon and cast members from Glee held a Kids’ Inaugural Concert at the Washington Convention Center for a crowd that included First Lady Michelle Obama and her daughters.
