Robert Pattinson and Kristen Stewart Join Katy Perry for Assistant’s Birthday Bash

The Robsten Reunited tour continued Wednesday night as lovebirds Robert Pattinson and Kristen Stewart joined friend Katy Perry at a birthday dinner for Perry's assistant in Santa Barbara, California.

In a blurry six-second video which ended up on YouTube, the three megastars are all seen celebrating the birthday of Tamra Natisin, Perry's assistant, who is a close friend of KStew. The two were seen palling around in L.A. while RPattz was off in Australia filming "The Rover" over the past two months.

It's important to watch closely, because the video is a blink-and-you'll-miss-it affair. Perry can clearly be seen on the right side of the table wearing a black-and-white striped shirt. She appears to be in a happy mood following her tough week in which her split with John Mayer was announced and her ex-husband Russell Brand made remarks about their former marriage in the press.

Pattinson is seated on the left side of the table, sporting a shaved head. Stewart stands up quickly from behind him and appears to be standing on her chair and reaching over her beau.

According to E! Online, the name of the restaurant they were at is called the Wildcat Lounge. An observer tells E! that the couple was affectionate and that they were "holding onto each other."

It's the second night in a row the pair has been seen out together. On Tuesday, they were spotted dining at Ye Rustic Inn bar in L.A.'s Los Feliz neighborhood.

Because the video is exactly six seconds long with momentary cuts, it probably originated as a Vine video and was then uploaded to YouTube. The person who posted it seems to be a fan, and calls themselves "LaSaga Robsten."
