Lindsey Vonn has found an unlikely singing partner in Hugh Jackman. The former Olympic skier, 36, and "X-Men" star, 52, teamed up to hit the slopes this past weekend -- and ended up partaking in a jam session where the duo sang along to Justin Timberlake’s "Can’t Stop the Feeling!" In the video, Vonn is seen jamming out on the piano and belting out the lyrics to Timberlake’s hit single from DreamWork’s "Trolls," while Jackman harmonized and violinist Grant Gardner played along.
