Los Angeles: Singer Beyonce Knowles was spotted working out with musician Paul McCartney at a gym here. If a source is to be believed, they had a number of sessions together.
"Jaws of guests dropped when they saw them together. They strolled in laughing and joking like old pals and hopped on the treadmill," contactmusic.com quoted a source as saying.
"Paul had a remarkably good pace. Beyonce then got off to join her trainer, who was trying to get Paul to join in. The pair then moved on to the studio where they stretched and did some gentle Pilates.
"People think it was a coincidence but it isn't the first time they have been to the gym together," the source added.
It is said Knowles and McCartney were also spotted together at a hotel here for Coachella Valley Music and Arts Festival.
