This is Kate Beckinsale. She an actress who has been in many, many films over the years.
And this is Sarah Silverman, the hilarious comedian who is currently dating actor Michael Sheen.
Michael Sheen and Kate Beckinsale used to date — and they have an 18-year-old daughter named Lily together.
So to recap: On the left is Lily, in the middle is Michael and Sarah, and on the right is Kate.
Kate, Sarah, and Michael are all super close, and Kate posted this photo on Instagram of a group of mad famous people hanging out.

Kate's reply?
Mom jokes for the win.
