They attended the star-studded premiere together on Sunday night.

He was not alone as he was joined by his 37-year-old friend and co-star Jonah who was accompanied by girlfriend Sarah Brady at the event held at The Paris Theater.
Don't Look Up - which was written and directed by Adam McKay - is centered around two low-level astronomers Dr. Randall Mindy (DiCaprio) and Kate (Jennifer Lawrence) who must go on a giant media tour to warn mankind of an approaching comet that will destroy planet Earth.
Leo looked dapper in a black coat over dark blue shirt with matching trousers and black dress shoes.
His brunette hair was combed over as he sported a blue protective face mask.
Jonah looked quite a bit more dressed down as he sported a grey jacket over a floral patterned button-down top.
He teamed the look with ripped blue jeans and black leather shoes.
The Superbad star also sported a purple beanie over his long locks along with a pair of brown plastic framed eyeglasses over his burly beard.
The actor was joined by 24-year-old girlfriend Sarah who wore a long beige duster coat over a black top and blue and white checkered jeans.
She finished off the look with black suede booties as she held onto a large leather bag.
The pair were the most talked about couple at the premiere the previous day as they sported matching light blue pantsuits and went shirtless underneath their blazers, which had gold buttons.
Leo was also at the gala event as he walked alongside pregnant co-star Jennifer Lawrence who dazzled in a gold Dior gown.
Don't Look Up is set for a limited theatrical release on December 10 and will be released on Netflix on December 24.
