Julianne Hough, Malin Akerman, & Ashley Greene Are the Women in Black at Katy Perry's Concert

Julianne Hough, Malin Akerman, and Ashley Greene are all matching in black while hanging out together on Friday (September 19) at the Staples Center in Los Angeles.

The ladies all enjoyed the Katy Perry concert from the private Hyde lounge hosted that night by Dell.

Earlier in the day, Julianne and Malin were both spotted out and about around town separately.

Julianne was seen heading to rehearsals for Dancing With the Stars while Malin met up with her friend Ken Marino for lunch.

FYI: Malin is wearing a Calypso St. Barth dress while out and about. Ashley is wearing a Mr. Kate necklace.
