14. Kelly Clarkson and Demi Lovato
Kelly paid tribute to Demi's birthday by covering her song 'Cool For The Summer' at a recent gig, and Demi took to Twitter to gush about how much she was in awe of Ms Clarkson. Demi posted, "WOW WOW WOW.. @kelly_clarkson thank you SO MUCH for covering #coolforthesummer at your show tonight!!! BEST BDAY GIFT EVER!! *literal tears*"… which kind of sucks for anyone else that got Miss Lovato a gift this year!
