No one likes a summer bug!

TMZ reports that John Legend was hospitalized in NYC on Sunday morning and was treated for flu-like symptoms.

Legend's rep tells Us Weekly that the singer is going to be okay and is resting up. "He's totally fine and at home -- just a flu-bug," the rep says.

On Sunday afternoon, the "Tonight (Best You Ever Had)" crooner tweeted about his health status. "Just got back to the U.S. Thanks to all my South African fans! I was a bit under the weather this weekend but you helped me through it," he posted to his Twitter account.

One thing is for sure: the Duets judge will be in good hands if his fiancee, Chrissy Teigen, is by his bedside to play nurse. The pair, who've been together for four years, got engaged while vacationing in the Maldives in December 2011.
