Caroline Flack's former boyfriend Lewis Burton and Louis Tomlinson's sister Lottie have grown close, it's claimed.
The pair were seen arriving at his flat together on Friday and appeared to be holding hands.
It comes five months after Caroline tragically took her own life at the age of just 40.
Lewis, 28, and Lottie, 21, are said to have bonded over their grief as she lost her mum Johannah Deakin aged 43 to leukaemia in 2016 and her younger sister Felicite, 18, died last year following a drugs overdose.
The couple reportedly started getting to know each other in May when they both attended a house party hosted by Caroline's close friend Lou Teasdale, 36, which was held to mark three months since her passing.
It's claimed some of their mutual friends aren't happy about their close bond.
A source told MailOnline : "They have been meeting up in secret for weeks but their newfound friendship hasn't gone unnoticed by mutual pals.
"Not all of Caroline's friends are happy with how the situation appears to be developing but can understand that both Lottie and Lewis have been there for each other as a shoulder to cry on.
"Lewis spent last week in Marbella while Lottie was in St Tropez the weekend previous, they couldn't wait to be reunited with each other on Friday."
Lewis has also been liking a string of Lottie's pictures, it's claimed.
Mirror Online has contacted reps for Lewis and Lottie for comment.
Lottie was one of ten friends who gathered at Lou's house in February to say goodbye to Caroline.
She had known Caroline for years after seeing her at celebrity parties.
Lewis has recently shown his admiration for Lottie by liking a string of her pictures, it's claimed.
Caroline took her own life in February weeks before she was due to face trial for assaulting Lewis.
Lewis had stuck by her, though they weren't allowed to see each other for months after her arrest.
An inquest into Caroline's death will be held on August 5 with a hearing at Poplar Coroner's Court in London.
