The Ray star sang the classic Eurythmics hit Sweet Dreams (Are Made of This) accompanied by the Preservation Hall Jazz Band at the Samsung Galaxy bash at a private residence in the historic Garden District of the city.

Foxx went on to perform a series of songs solo before being joined by his Dreamgirls co-star Hudson and the pair thrilled the crowd, including hip-hop star Flo Rida, actor Kellan Lutz and actress Olivia Munn, according to New York Post gossip column Page Six.

Performing in public is becoming a regular event for Foxx, who earlier this year (21Jan13) serenaded U.S. Vice President Joe Biden and his wife Jill at President Barack Obama's Inaugural Ball.
