Perry performed at the Staples Center here on Friday -- the same day when singer Taylor Swift released her album "Reputation" with a song trashing Kim and her husband Kanye West, reports tmz.com.

In some photographs, Kim and North can be seen enjoying Perry's concert and posing for selfies with her. Kanye was nowhere to be seen at the concert as Friday was his mother Donda West's 10th death anniversary.

In a song, titled "This is why we can't have nice things", Swift slammed West in particular for secretly recording her during a phone call last year.
