Robert Pattinson, Kristen Stewart and Katy Perry partying in Santa Barbara

Robert Pattinson
and Kristen Stewart are certainly enjoying their time together after spending more than two months apart. The only problem was their best mates, Danielle Coughlin and Sarah Tucci-Barbaro were unable to make it. confirms the Twilight twosome went to the Wildcat Lounge in Santa Barbara last night for a quiet happy hour together, where an eyewitness says the lovebirds were being affectionate and “holding onto each other” (so sweet!).

After, Rob and Kris joined pals Katy Perry, Shannon Woodward and more to celebrate the birthday of the “Fireworks” singer’s assistant, Tamra Natisin.

A mega-Robsten fan captured a few moments of the festivities in a six-second YouTube video, where Rob and Kris are clearly seated at the dinner table beside each other. Perry’s BFF Shannon also posted a few silly clips from the celebration last night on Twitter.

The latest Robsten sighting comes on the heels of the couple’s romantic Los Feliz date night, where they hung with friends at one of their favorite local bars, Ye Rustic Inn.

R.Pattz returned to the States over the weekend after spending ample time Down Under filming his upcoming flick, The Rover.

Apparentally Robert is  is “so excited to be back” and he “really missed Kristen.”
