Tipperary-born singer Una Healy of girl group The Saturdays left Justin Bieber red-faced after obsessing over his smooth cheek and baby “soft skin”.

Speaking on on E! Entertainment show Fashion Police, Una told host Joan Rivers: ''We met Justin Bieber, he was on a TV show with us and I remember I went in for the kiss on the cheek and he's got baby soft skin!''

Her bandmate Rochelle Humes, who is expecting a child with JLS star Marvin Humes, added ''You were so creepy though. She said to him,'Your skin is so soft!' Don't tell him that!''

The British girl band appeared to be just as star-struck when they met Free Fallin' singer John Mayer in Los Angeles while filming their new reality show Chasing The Saturdays.

Mollie King explained: ''We saw him the second night we were here and he was at the same place we were having dinner. I was sat with my back to him and was like, 'Girls, move round the table!' Everyone had to play musical chairs so I could see him.''

Meanwhile, former S Club 8 member Frankie Sandford joked: ''She didn't just stay at the table, she then had to do a swoop of the whole restaurant, 'Is he still there?'''

Chasing The Saturdays premieres on Sunday February 3 at 10pm on E!.
