Maya Jama showcased what appeared to be an engagement ring as she walked the red carpet at the Brit Awards.
The TV presenter, 27, reportedly became engaged to American basketball player Ben Simmons, 25, over the festive period.
Neither has so far confirmed the reports.
Simmons, who plays for the Philadelphia 76ers, is signed with sports agency Klutch Sports, which is primarily owned by Rich Paul, the boyfriend of Adele.
Jama posed for the cameras outside London’s O2 Arena with the large ring clearly on show, wearing a revealing black outfit that featured a black crop top.
The piece was reminiscent of the so-called Mohawk dress by Bob Mackie that Cher wore to the 1986 Oscars.
Host Mo Gilligan poked fun at Jama, saying: “I can’t have you here without talking about that amazing rock on your finger.
“Listen, that is the size of a small studio bedroom flat in London, it looks fantastic though, you’re working it.”
Swatting away his engagement-related jokes, Jama said: “Alright, let’s move on.”
Jama parted ways with ex-boyfriend Stormzy in summer 2019, after more than four years together.
She and BBC radio DJ Clara Amfo were tasked with welcoming award nominees to the arena during the official red carpet show.
