The Teenage Dream singer, 26, was joined by husband Russell Brand, who had just hosted Saturday Night Live the night before, and her grandmother, Ann Hudson, at Sunday’s ceremony from L.A.’s Staples Center.
“If I don’t go home with any Grammys, I still go home with my Grammy,” she told E! host Ryan Seacrest.
And they weren’t just gushing over her Grammy nods. Perry’s very special red carpet escort was celebrating her 90th birthday, the singer said. (Last month, they marked the milestone at the Cirque du Soleil Viva Elvis show in Las Vegas.)
What did Perry give her grandma for the big day? Hudson made the red carpet rounds with a bedazzled walking cane, courtesy of her granddaughter, and the group wore coordinating Armani outfits.
With her real Grammy by her side, Perry says, “it feels amazing” to be nominated and recognized by fellow musicians.
“You feel popular, I guess,” she said.
