Kristen Stewart reunited with Robert Pattinson in London!? 'Twilight' starlet spotted boarding private plane in LA, ready for holiday romance with on-and-off again beau?

So, here is what's going on with the entire Robsten sitch.

After breaking things off earlier this year, K-Stew and R-Patz secretly rekindled their romance (allegedly). Apparently, the Camp X-Ray starlet cooked an amazing feast for the British heartthrob on Thanksgiving. But just a few days later, the British hottie jetted-off to London to spend some time with the fam... 

And now, Stewart might be on her way to join him. Check out the airport photo here. It remains unconfirmed if the 23-year-old actress actually boarded a plane to London, but anything's possible, right?

Pattinson recently called K-Stew for a little flirty phone chat, so maybe that's what motivated Stewart to rejoin her beau across the ocean:

"Rob reached out to Kristen to congratulate her for Camp X-Ray being selected for Sundance," a HollywoodLife insider explains. "They talked for awhile and by the end of the conversation he invited her to come see him in London. Not sure if she's 100% going to take him up on it, but she was just so happy." 

Just a few days before this, another source claimed that K-Stew was "upset" she wouldn't be able to see R-Patz anytime in the near future:

"Kristen won't see Rob for a while now - he will spend the Christmas holidays with his family and then start filming Queen of the Desert. I am sure if Kristen was invited to join Rob in London she would gladly go but there was no invitation. At first she was upset he was leaving the country for the rest of the holidays but she's trying to stay positive. She's got a ton of really supportive friends she can lean on. There's no set date yet on when Rob and Kristen will see each other again."

Well, what do fans think? Is Stewart joining Pattinson in London for a romantic holiday reunion. Wonder what Pattinson's family must think if that's the case!
