The phrase "Vegas at the Mandarin" became more than just a line in Maren Morris' song "Rich" over ACM weekend earlier this month. 

We just found out that's where the New Female Vocalist of the Year held an early birthday celebration with family and friends. Just nine days shy of her 27th birthday, Maren hit the rooftop of the Mandarin hotel in Vegas to celebrate the past year of her life.

She even managed to chow down on a tiramisu cake, topped with a longhorn skull, which was inspired by the tattoo on her inner bicep. (People)
