They're being dubbed 'one of the hottest couples in fashion' by the few who know.
But Jourdan Dunn's relationship with fellow model Younes Bendjima came to light on Tuesday, when reports in The Sun newspaper suggested the pair have been dating since the summer.
British beauty Jourdan, 25, and 22-year-old Algeria-born Younes, who formerly trained as a boxer, met at a Met Gala 2015 afterparty in May and recently rang in the new year in Bali together.
A source told the newspaper: Jourdan keeps her private life closely guarded but she's really taken by Younes.
'They have spent a lot of time together since they met and despite their work commitments have managed to carve out a relationship.
'It's got more serious since the summer and they've been described as one of the hottest couples in fashion by those that know in the industry.'
MailOnline has contacted a spokesperson for Jourdan Dunn for comment.
New York and Paris-based Younes joined Jourdan and a set of model friends for an exotic break to the Indonesian island of Bali in late December, being pictured with arms wrapped around each other on the beach.
Their supposed relationship has stayed extremely covert, perhaps thanks to her single parenting duties back in the UK.
Jourdan is mother to six-year-old son Riley, from her previous relationship with Jordan Cummings, who was charged with drugs offences just two months after the birth of their child.
When she dated Liverpool striker Daniel Sturridge, with whom she split in May 2014 , sources claimed she was 'cautious about letting new men into her life' and therefore kept her love life quiet.
Younes and Jourdan seem to have plenty in common, thanks to their respective, growing modelling careers.
Former boxer Younes, who previously worked in his father's restaurant and is now good friends with British popstar Rita Ora, was scouted in New York City in 2011.
Meanwhile, Jourdan was discovered in London's Hammersmith while shopping at the age of 15 nine years ago.
Her new modelling beau has appeared in the Missoni S/S 15 Men's Show and Marcelo Burlon F/W 14, after making his debut walking for Givenchy's Spring/Summer 2013 catwalk.
Jourdan's profile is still growing and she covered her first solo British Vogue cover in February 2015 and won Model of the Year for a second time at the British Fashion Awards last November.
