The Wanted singer, 33, recently split from girlfriend Stacey Giggs after they rekindled their relationship in April following the death of his bandmate Tom Parker, who tragically died due to a brain tumour.
Now it has been claimed that George has begun a new relationship with former the 21-year-old former EastendEstenders star after the pair were allegedly “all over each other” on a flight to Crete last Sunday.
Despite alleged attemps to go incognito with George sporting a bucket hat and Smith wearing sunglasses, they were spotted by fellow passengers who claimed the pair were “all over each other” as they flew from Manchester to the Greek island.
A passenger told The Sun: “They looked like a very loved-up couple — they were all over each other for the entire four-hour flight.
“Snogging and giggling like any new couple.”
George and Smith appeared on the 2020 series of Strictly Come Dancing together.
They are believed to have got close during the Strictly Live tour which started in January this year when Smith was announced as a last-minute replacement for TV presenter AJ Odudu, 34, who injured her ankle.
They then went on to appear together in a 35-date live tour — Strictly Presents: Keeeep Dancing — during June and July.
An insider told added: “Maisie and Max knew each other on Strictly back in 2020 but they were both so busy on the show they never got to know one another properly.
“But on the Strictly live tour at the start of the year they became good friends.”
The source insisted the relationship only began once George had split from Giggs, but says “it got serious pretty quickly.”
Adding: “Maisie and Max are acting like love-struck teenagers. Their close friends and family have known they are together for a while and are pleased for them.”
The Standard has contacted representatives for Max George and Maisie Smith for comment.
