Rita Ora could barely contain her grief while tributing Liam Payne at MTV's European Music Awards Sunday ... choking up as she lauded her late pal for his positive personality.

The singer-songwriter -- who hosted the show in Manchester, England -- took the stage during one break and highlighted Liam, who passed away after falling from a hotel balcony last month.

Sabrina Carpenter, Shawn Mendes and Camila Cabello lit up the VMAs with their performances ... serving up a juicy love triangle playlist that had everyone reading between the lines.

Shawn then followed with a performance of "Nobody Knows," with lyrics like “flying too close to the sun” -- an apparent nod to Camila’s IG bio, which reads, “long, thick black hair turned white from flying too close to the sun.”
