Neither one nor the other went public to confirm it, but that did not stop people from deciding that it was true.
Beckinsale seems determined not to let people talk about it, it does not matter.
The Instagram account CommentsByCelebs keeps track of some of its backs.
After the actress of "Pearl Harbor" published the photo of a woman resembling her with an owl on the shoulder, a disciple commented, "Dear God, Kate, not Pete Davidson."
"No, it's my mother," Beckinsale replied. "Easy mistake."
When someone else commented on another photo, writing "Disappointed by your choice of dating with a friend", she replied with "Quite disappointed by your stupid beard, but I have thought impolite to say "
At least one person seems to be in favor of a possible relationship between Beckinsale and the star of "Saturday Night Live".
When TMZ asked her what she thought of the possibility that they were a couple, singer Ariana Grande, a former Davidson fiancée, said "So cute!"
