Hilary Duff’s boyfriend jokingly mocks her in latest Instagram and we’re skitting

We think she's got herself a good 'un.

There's nothing better than a celebrity couple that can tease each other in good faith. Ellen and Portia do it, Kim and Kayne and of course, Ryan Reynolds and Blake Lively are King and Queen celebrity roasters. Since her days on the hit show Lizzie McGuire, we've been avid fans of Hilary Duff and think it's so cute that she's now a mum to two beautiful children. The 31-year-old actress and singer recently uploaded a stunning picture of her youngest child, little Banks. While the photo was adorable, there was one thing that caught our eye even more - a comment left by Hilary's current boyfriend and Banks' Dad. Hilary's beau, American musician Matthew Koma, commented:

"Hey what filter is this? You look just like a baby lol."

And this isn't the first time he's shown how witty he is. In what we think could have just been the best caption of the year, just after Banks was born in October, Matthew posted a picture with his little girl and jokingly poked fun at Hilary saying, "She said she didn’t want a serious boyfriend lol." Last month he uploaded a picture of an unhappy looking Banks captioned,

"When I told her I’m her dad."

Hilary has previously said that Matthew is taking to fatherhood exceptionally well and is very caring to both her and Banks. Too cute!
