The couple are said to have shared an emotional, hour-long phone call with Rob confessing he "felt sad" for his cheating ex.
"She begged him to meet face-to-face so they could talk. It was obvious Kristen was getting through to Rob and he agreed to see her," a friend of the couple told Look magazine.
The 26-year-old actor reportedly feels Kristen deserves a little sympathy, given she has been nicknamed a "trampire" following her controversial affair with Snow White director Rupert Sanders.
"He admitted it must be worse for her because she's not just dealing with heartbreak, but being portrayed as a villain, while he gets all the sympathy," said the friend.
"For the first couple of weeks he was wallowing in his own grief, but being forced to face people during [his Cosmopolis] promo, and seeing how angry everyone is with Kristen made him feel sad for her."
If Kristen can manage to convince Rob to look her in the face, the question begs, will she be able to get him back?
The actor is reportedly showing signs he hasn't given up on his 22-year-old former love, with a source telling Heat magazine he has been wearing her sunglasses.
"Rob and Kristen always wore each other's clothes when they lived together, and the fact that they've not stopped doing that could be a signal that it's not over between them," said the source.
But before Twilight fans rejoice in the possibility of their favourite on-screen couple reuniting, Kristen will have to agree to a few terms and conditions. British-born Rob is reportedly demanding that the duo spend more time in London than Los Angeles if they get back together.
The former couple haven't decided where they'll meet to discuss their future together but are reportedly considering Reese Witherspoon's ranch, where Rob is said to have hidden out following news of K-Stew's fling.
