The TikTok star and Miami Dolphins receiver eliminated any doubt about whether they're actually a couple at the sports award show ... with their appearance being considered a "hard launch" for their relationship.

The two initially sparked dating rumors following BB's split from Olivia Culpo's younger sister earlier this year ... which resulted in numerous cheating allegations from Sophia.

Braxton has adamantly denied being unfaithful at any point in the relationship ... and Earle insisted she is not "dating" the footballer, despite including a short snippet of them hugging in a TikTok posted to her page on June 25.

But let's be real -- they certainly looked like BF and GF as they dressed up in sharp outfits for the event ... posing for pics together before entering the Dolby Theater.

Sophia has seemingly decided to chill on posting any drama-related content surrounding Berrios and Earle's appearance ... but that could always change.

As for Earle, she shared a vid of her prep for the big night ... and revealed the couple had a 6 AM flight they'd most likely miss Thursday morning.
