Katy Perry on Ariana Grande's 'boss move' when they ate separately at same restaurant

The singer said Grande surprised her by picking up her dinner tab.

Katy Perry talked friendships and random acts of kindness during a recent appearance on the "Ellen K Morning Show".

The singer, 34, shared that she recently bumped into Ariana Grande, 26, while they were both dining at a sushi restaurant, and the singer surprised her party with a sweet gesture.

"At the end of my long meal with Orlando and his son, we finished after an hour and a half and we asked for the check, and they're like, 'Ariana Grande has taken care of it.' And we're like, 'Oh my god! That's so cool!''" she shared, mentioning her fiancé Orlando Bloom.

"Orlando's son is 8, so I think he was like, 'Dope,'" Perry added. She said that Grande's treat was a "a boss move" and "such a cute gesture."

"Orlando was like, 'Man, I have such mad respect for her,'" Perry added. "She was so kind -- I love little things like that. Just grateful for this whole experience.”

She revealed that close friend Ryan Seacrest had also pulled off the surprise move. He picked up the tab at a group dinner she had in New York City with him and fellow "American Idol" judge Lionel Richie.

"He's tried and true. People just feel like he's a part of their family, and he never lets anyone down," she said about Seacrest.
