The 45-year-old comedian has become quite close with her boyfriend's ex, and has even started to exchange jokes with her on Instagram. On Tuesday night, Beckinsale Instagrammed throwback pics of herself and Silverman, and called out their similar retro hairstyles.
"Oh @sarahkatesilverman if only I had known you then," the 43-year-old actress wrote. "We could have supported each other through the ennui and tall,unfortunate hair we were clearly both experiencing."
Silverman responded: "Oh my sweet lord Jesus, this makes me joyous."
The Wreck-It Ralph star also posted a NSFW text message exchange with Beckinsale that the Underworld star called "the second best collage" she'd received from her friend. "@sarahkatesilverman you absolute HUNK OF BURNING LOVE," she gushed.
