Jennifer Lopez Performs Her Song 'All I Have' at Sundance Party
JENNIFER LOPEZ IMPROMPTU PERFORMANCE AT SUNDANCE

Jennifer Lopez surprised partygoers in Utah over the weekend with an impromptu performance of one of her longtime hit songs at the Sundance Film Festival.
J Lo was at Tao in Park City on Saturday night where she surprised clubgoers by getting behind the DJ booth for 10 minutes and surprised fans with a performance including singing her 2002 single, "All I Have."
The singer, who's in town for the Sundance Film Festival, posted several snaps on her Instagram from the club where she partied the night away sipping Casamigos cocktails and dancing with her best friend, Stevie MacKey.
Lopez has been keeping busy lately. She made the flight from Los Angeles to Park City after stepping out to celebrate her manager Benny Medina's birthday in Beverly Hills on Friday night.
We broke the story last week ... J Lo may have found an off the market $20 million home home in Brentwood she may purchase.
