Though the couple broke up in April, they are both following each other on Instagram.
Davidson reportedly started following Beckinsale on Instagram in the early hours of Tuesday, Page Six reported.
The 25-year-old “Saturday Night Live” star also liked one of Beckinsale’s posts, showing pictures of the “Pearl Harbor” actress with her parents.
Beckinsale, 45, also liked a photo of Davidson that the comedian had posted early Wednesday.
A source told Page Six that the couple split because of the public attention over Davidson’s life.
“Even though Kate has been in Hollywood for a long time, she struggled with the attention on her relationship with Pete,” the source told Page Six. “He lives his life with his heart on his sleeve.”
A source close to the couple told ET Online in April that the duo are no longer in a romantic relationship. However, the source noted at the time that they were still friendly with each other and on good terms.
The comedian posted a video on Instagram when he was supposed to be performing at the Stress Factory Comedy Club in Bridgeport, Connecticut, accusing the venue of disrespecting him.
"Hey guys in Connecticut, I'm sorry that we had to leave the show before I got to go on. The owner, Vinnie Brand, disrespected me and did something I told him not to do, and I can't perform under those circumstances," Davidson said in the clip.
