The singer actually brought her brother, David Hudson with her, and even shared a silly photo from inside the limo just moments before they stepped out onto the red carpet.
Don't worry, though, Katy met up with boyfriend John Mayer at the Grammy after-party and by all accounts, it seems like they had an absolutely amazing time!
This isn't the first time Katy has brought a family member out on the red carpet with her. In fact, Katy's grandmother has accompanied her to two major events--the 2012 Billboard Awards and the Smurfs premiere.
The superstar also had her family in tow for her Part of Me premiere in 2012.
We think it's sweet that she lets them share the spotlight with her!
