Amanda Seyfried, Katy Perry and Nicki Minaj Lead Today’s Star Sightings

The stars have all been working hard for the last 24 hours.

Amanda Seyfried continued her promotional tour for her latest flick, Lovelace, this week by attending a special screening in London. Also staring Peter Sarsgaard and Sharon Stone, the movie centers around the life and times of adult film actress Linda Lovelace and her struggles with abuse in the porn industry.

Stateside, Katy Perry — and her giant golden semi — hit New York City to promote her upcoming album, Prism. Clad in a crushed velvet dress, the “Roar” singer was spotted signing autographs and taking pictures with fans.

In Miami, Nicki Minaj was busy filming a new music video for DJ Khaled’s “I Wanna Be With You.” Though she was snapped wandering around set wearing a thick white robe, the rapper gave fans a glimpse of the killer outfit underneath on her personal Instagram.
