Pop singer Jason DeRulo didn’t let a recent neck injury stop him from attending Muhammad Ali‘s big “Celebrity Fight Night XIII” event with his girlfriend Jordin Sparks Saturday night (Mar 24) at the JW Marriott Desert Ridge Resort & Spa in Phoenix, AZ.

Jordin was dressed up in a long, animal print gown, while Jason — who injured his neck earlier this year while rehearsing for a tour — had on a fancy leather neck-brace to match his black and leather-trimmed tuxedo.
