LeAnn Rimes is All Smiles at Sundance

LeAnn Rimes was in high spirits as she made an appearance at the Sundance Film Festival in Park City, Utah on Monday. Even while being pushed and pulled by security to get through the crowd, the country singer continued to keep a smile on her face! LeAnn performed at the festival among a mix of other artists including: The Fray, Brendan Benson, Richard Mark, John Forté and Grace Potter and the Nocturnal. Must have been a great show!
