Last night, “Crazy Rich Asians” star Gemma Chan, 36, and “Mamma Mia! Here We Go Again” star Dominic Cooper, 40, made their first public appearance together!

After months of rumors, Gemma and Dominic stepped out for a Fashion Awards after-party, looking like a million bucks!

Gentleman Dominic was seen opening the car door for Gemma.

In August, Dominic and Gemma sparked rumors after they were seen getting cozy in Formentera. At the time, a source told The Sun UK, “Dominic is very recognizable — especially with 'Mamma Mia 2' out at the minute — so it didn’t take long for people to notice him. He and Gemma looked as though they were having a great time — laughing loudly and cuddling up while taking pictures.”

The two co-starred in the 2017 film “Stratton.” Dominic has a history of dating co-stars, including Ruth Negga and Amanda Seyfried.
