Roman Kemp and Love Island star Maura Higgins reportedly "grew close" while attending a BRITs after-party last week.
The 29-year-old DJ is believed to have met the 32-year-old Ann Summers model at London's O2 Arena before they both headed to singer Tom Grennan's after-party.
They had headed to the party in Soho along with Roman's colleagues Sonny Jay, 28, and Sian Welby, 35.
A source told The Sun : "Everyone was talking about how Maura and Roman were flirting and all over each other during the bash.
"They were dancing together and laughing a lot, they seemed to be glued to each other’s sides all night."
The insider added that hanging out with Roman appeared to put a smile on Maura's face again.
However, a spokesperson for Roman told The Mirror: "Roman and Maura are just friends."
It comes after Maura's ex Giovanni Pernice was reportedly spotted snogging Emily Atack at The Box nightclub nearby.
However, the Strictly pro appeared to laugh off the rumours by using ABBA's hit single Mamma Mia to send a cryptic message to his fans.
An onlooker at the same party as the two stars on Tuesday night told The Sun : "Gio and Emily were snogging the faces off each other. Their hands were everywhere and they were absolutely loving it."
Posting to his Instagram Stories on Thursday, Giovanni - who split from Love Island's Maura Higgin's last year - seemed to laugh off the reports.
Sharing a Memoji of himself crying-with-laughter, the professional dancer used following lyrics from the ABBA hit single Mamma Mia as a soundtrack: "Mamma Mia, here I go again. My, my, how can I resist you? Mamma Mia, does it show again? My, my, just how much I've missed you?"
Giovanni wrote "That's all..." underneath his Memoji and the song's lyrics.
