Now that it has been reported that Robert Pattinson is engaged to FKA twigs, it is rumored that the actor's ex girlfriend, Kristen Stewart, is leaning on "Twilight" co-star Taylor Lautner. 

According to HollywoodLife.com, Lautner immediately "reached out" to Stewart after finding out about the British couple's engagement on the Internet. He reportedly offered support and reminded her that it is not her fault.

The pair has maintained a close relationship ever since starring in the popular vampire fantasy film series together, comforting each other in times of trouble.

"He's been there with her throughout all the ups and downs with Rob and totally understands how the news is playing with her head," an insider claimed. "He's always been like her rock and [vice] versa."

The publication recently reported that the "Still Alice" actress "felt devastated" hearing that "The Rover" actor and the "Pendulum" singer are getting married.

Stewart, who dated Pattinson for years, was allegedly in disbelief because her former lover ended up proposing to FKA in such a short period of time. A source revealed that she is "especially hurt" because they also talked about possibly getting married. 

The two ended their relationship after Stewart had an affair with her "Snow White & The Huntsman" director, Rupert Sanders. Although they were still seen together after news broke, they eventually broke up. 

"She knows it's her fault she never got to marry Rob, but still hearing that he's engaged still really stings," the source added.

After getting his heart broken, Pattinson supposedly did not feel the need to tell Stewart about his engagement to FKA twigs.

"Kristen was not told -- he didn't reach out to her and tell her," another source said. "That ship has sailed. He doesn't talk to her -- they have two completely different lives. She is not a part of his day at all. FKA is his life now."
