James Arthur was spotted kissing a mystery brunette during a night out.

The 'X Factor' contestant spent Thursday night (29.11.12) partying at London's upmarket Mahiki club with fellow hopefuls Union J when he was seen planting a kiss on the lips of a tanned brunette girl as they stood in the smoking area.

James, 24, even bought his lady friend a single red rose - which she clung on to throughout the evening.

After previously revealing he once thought he was too ugly to be a successful singer, James seems to be relishing in the celebrity lifestyle, but still insists he is not a womaniser.

He told Heat magazine: ''I didn't commit any crime - I'm young and I'm single and you only live once. I've only been out once or twice since I've been [in London].

''I had a proper blow-out that night and got pretty drunk and probably went a bit too far. Unfortunately, it might have tarred me with a bit of a womaniser brush.''

Union J's George Shelley laid rumours of a possible romance between him and 16-year-old contestant Ella Henderson to rest as he was accompanied by mystery blonde as they walked hand-in-hand, wearing matching leather jackets.

James - along with Union J, Christopher Maloney and Jahmene Douglas - will battle it out in the semi-final shows this weekend (01.12.12) and the wannabe singer urged his fans on Twitter to vote for him to go through to the final.

He posted: ''All you people who wanna see me in the final please pick up the phone this weekend! I really wanna be there! Who's gunna get the album!?! X(sic)''
