Robert Pattinson and Kristen Stewart are "100 Percent Together,"

What does Oprah Winfrey have to do with the status of Robert Pattinson and Kristen Stewart? Allow us to explain:

These two have already taped their appearance on Oprah's talk show (it will air on May 13, Robert's birthday! Eek!). Prior to taking the stage, as usual, the guests met with the host and went over what questions will be asked in front of the studio audience.

Winfrey warned that the topic of Rob and Kristen's relationship would come up. She had to "go there." But she'd allow the couple to be coy with their answer (they actually joke about Kristen being pregnant on the air) as long as they gave Oprah the actual answer off camera.

"Both Rob and Kristen's people and Summit then confirmed ahead of time [Rob and Kristen] are together and are dating. One hundred percent," a source told E! News.

This should close the case of Robsten forever. After all, who lies to Oprah?!?

As for the interaction between the love birds, this same insider revealed: "They weren't super affectionate or anything. Kristen seemed a little awkward and nervous, but Rob didn't at all. He was really friendly and was cracking jokes the entire time."

Sounds like the personalities of each star that other sources have also confirmed. Will you tune in for their appearance on Oprah? Or, here's a better question:

How many times will you watch their apearance on Oprah?
