Coldplay singer Chris Martin serenades MLS star Lionel Messi, his wife at concert

Messi and Roccuzzo smiled waved to the packed house that cheered them both on while they were shown on the jumbotron. Coldplay lead singer Chris Martin serenaded Messi and called him the "No. 1 sportsperson of all time."

Messi's appearance came in the midst of controversy in Major League Soccer.

Messi, and his Inter Miami teammate Jordi Alba, were suspended for one match last week after they decided to skip the Major League Soccer All-Star Game, which included a match against the stars from Liga MX of Mexico. Messi didn't play amid a packed schedule in the U.S. and abroad while Alba was dealing with a previous injury.

Any player who doesn't participate in the All-Star Game without approval from the league is ineligible in their club's next match.

"I know Lionel Messi loves this league," MLS Commissioner Don Garber said. "I don't think there's a player - or anyone - who has done more for Major League Soccer than Messi. I fully understand, respect, and admire his commitment to Inter Miami, and I respect his decision.

"Unfortunately, we have a long-standing policy regarding participation in the All-Star Game, and we had to enforce it. It was a very difficult decision."

Inter Miami and Cincinnati played to a 0-0 tie on Saturday.
