What does Ben Stiller really think of Focker-in-Law co-star Ariana Grande?

Ben Stiller thinks Ariana Grande has something "very special" as an actress.

The 60-year-old actor worked with the Thank U, Next hitmaker for the first time on Focker-in-Law and he was blown away by just how "good" she is on screen.

He told Extra: “She just has something in terms of an innate sense of, as an actor, how to make a scene come alive and be specific and she just shines through.

"And she's funny, she has a great sense of humour, and she's just so much fun to work with. She's got something very special. I'm not the first person to say that, but as an acting partner, I loved working with her.”

And Ben was delighted to reunite with Robert De Niro once more on the latest film in the Focker franchise.

He said: “We come back together on these movies. It’s been fun to kind of have that experience of growing older with the character and the changes in life that he’s going through.

“To get to this point where Greg is basically the age that Jack was… and in a similar position, it's crazy.

“I look at Bob and he’s so vivacious and young… He really is still just Bob.

“He’s so sweet and so loyal and such a good friend to anyone whom he loves and he’s connected to, and he’s such a generous guy.

"There are a lot of people he feels that way about, and I’m just happy to have that connection with him and I always love seeing him.”
