The 34-year-old actress and the 30-year-old rapper - who started dating earlier this year - are both set to appear at the American Music Awards in Los Angeles.

Megan - who has Noah, eight, Bodhi, six, and Journey, four, with Brian Austin Green - will be a presenter at the glitzy bash, according to People.

Kelly - who released his latest album, 'Tickets to My Downfall', in September - is set to make his debut at the American Music Awards and perform during the ceremony.

The upcoming show will be the celebrity duo's first major appearance together since they began dating during the summer.

In recent months, they have both been gushing about each other in interviews, with Megan saying they have a connection of "mythic proportions".

She shared: "The intensity of merging with him is just overwhelming, and the threat it poses is so powerful but so beautiful that you have no choice to surrender with reverence and with gratitude."

The Hollywood star also recalled how she felt when they first met.

She said: "I looked into his eyes [and] I felt the most pristine, most gentle, most pure spirit.

"My heart shattered immediately and I just knew that I was f*****."

Meanwhile, Kelly admitted that their romance caught him by surprise.

The music star confessed he wasn't expecting to find love amid the coronavirus pandemic.

He previously explained: "Everything now is isolation, dehumanisation, separation. And f***, dude, you have in your head that you're this rock star, with multiple women and all that.

"So finding someone that can take you out of the fast lane and make sure that you're safe, because at any minute you can crash — I love that it can evolve into that."
