Jonah Hill goes retro in tie-dye as he puts on a romantic display with fiancée Gianna Santos

Jonah Hill has been getting plenty of quality romantic time with fiancée Gianna Santos during isolation.

And the soon-to-be newlyweds appear closer than ever, as they reemerge from quarantine to see friends.

He went retro Tuesday in a tie-dye t-shirt, as he put on a romantic display with Santos, while social distancing with pals at an outdoor birthday party in Los Angeles.

The 36-year-old paired the colorful top with some purple basketball shorts and white trainers with black tube socks.

He finished the look with a white baseball cap and brown glasses with transition lenses, as they took precautions from COVID-19 in white face masks.

Hill affectionately wrapped his arms around Santos, 31, as they stood at the curb to keep a safe distance from others. 

Their engagement was announced last September, after they were first romantically linked in August of 2018.

The Superbad actor recently made his footwear debut, designing a Superstar Sneaker for a collaboration with Adidas. 

Inspired by his ’90s adolescence on the West Coast, he said: ‘I started thinking back to all the experiences I had growing up while wearing them, and tried to make my fantasy version of what I would have wanted when I first wore them.’

Hill pledged to donate 100 percent of his royalties from the shoe to Black Lives Matter, amid nationwide protests over the killing of George Floyd.

He confirmed the collaboration back in January, posting to Instagram: ‘Thank you adidas for trusting me and believing in my ideas and pushing them to become even better.

‘This is a dream for me to start the journey of creating with a team I respect and love.’
