This is Dane Cook and his girlfriend, Kelsi Taylor.
They've been dating since early 2018.
He's 47 and she's 20.
Dane is always leaving cute comments on her Instagram pictures.
Like the time Dane responded to this picture with, "This pic is completely sasstacular."
"If this is what rock bottom looks like I'm on my way!!"
"I love you more than our haters hate us!!"
He even comments on where she tags him in her pictures.
It's definitely very interesting!
Dane was on The Tonight Show Starring Jimmy Fallon and talked about how people get a little "persnickety*" about one detail of their relationship.
*According to Merriam-Webster, "persnickety" means "fussy about small details."
