Robsten fans have a lot to cheer about!
Following a sighting at a karaoke bar in Los Angeles, Robert Pattinson and Kristen Stewart stepped out together again Wednesday night, joining Katy Perry at a birthday dinner for the singer’s assistant, Tamra Natisin.
In a six-second video posted online, Perry, in a striped shirt, leads the table in singing “Happy Birthday” to Natisin, and presents her with a chocolate cake while Stewart appears to snap a photo of Pattinson, who is seated near the birthday girl.
It was a fun night night out with friends for Perry, who recently split with John Mayer after dating for seven months.
