Irish singer Van Morrison has been awarded the prestigious Johnny Mercer Award while Lady Gaga received Contemporary Icon Award at the 46th annual Songwriters Hall of Fame ceremony in New York.
The 69-year-old singer, Morrison, received the award for his "outstanding creative works", reported Telegraph.
Gaga, 29, was presented with the award by her 88-year-old singing partner Tony Bennett.
The "Born This Way" singer performed a version of Linda Perry's "What's Up", before presenting her idol with Songwriters Hall of Fame inductee award.
Perry then returned the favour, performing a slowed down rendition of Gaga's "Bad Romance", before she was given her award by Bennett.
Other Songwriters Hall Of Fame inductees include country music stars Toby Keith and Bobby Braddock, Cyndi Lauper, blues legend Willie Dixon, the "Grateful Dead" songwriting team of Robert Hunter and the late Jerry Garcia.
