Kylie Minogue's new romance reportedly has close friends concerned.

The 47-year-old singer has been spotted in the company of British actor Joshua Sasse, who is 20 years her junior, recently. They met on the set of American TV series Galavant and have seemingly grown close since.

However Kylie's pals are rumoured to be worried about her blossoming relationship due to the age gap.

"Kylie's friends want to see her happy and settled, but they're concerned that by going for someone so much younger, she risks getting her heart broken again," a source told Britain's Closer magazine. "They think she needs to slow down her hectic schedule and find a man her own age, who is husband material."

Kylie's love life has been in the spotlight since she found fame in Australian soap Neighbours. She previously dated her co-star Jason Donovan and had high profile relationships with actor Olivier Martinez and model Andrés Velencoso.

According to the source, Kylie has no concerns about being with Joshua, 27, due to their special bond.

"Kylie is really falling for Joshua. She knows there's a massive age difference between them, but she's told friends that age means nothing when you have chemistry," they added to the publication.

"They started hanging out on [the Galavant] set, then were both out at a party together, where they spent all night talking. Kylie has been swept off her feet. She loves that Joshua is young and hot - he's a massive boost to her confidence."

The Locomotion singer has been open about her desire to settle down in the past. It was only in May (15) that she admitted she's got a great career but doesn't have the children or firm relationship she desires.
