The spotting came the same week a report came out that the couple plan on having a baby and raising it in Pattinson's native country.

According to a report, Stewart wants to start a family and raise their child in London and the British hunk is ok with it as long as she never cheats on him again.

"They were talking about their future and Rob told her that as long as she stays true to him, he's willing to have a baby with her," a source reportedly told OK! Magazine.

And Stewart is said to be persistent about the matter because she's grateful that Pattinson has given her a "second chance at life."

"She feels like she's getting a second chance at life," the source added. "Now that they're back in a good place and planning their family, she feels alive again. She says she started crying when Rob told her."

"Rob is very patriotic and he feels like an English childhood is the be-all and end-all," the source continued. "Kristen loves it there too and she feels her baby would have a better shot at a normal upbringing in Europe."

The source further added that the couple were planning to build a "lavish nursery" in anticipation of a pregnancy, but Stewart is hoping that Pattinson would marry her first.
