Here boy!: Tulisa Contostavlos arrives at the X Factor house with her pet rottweiler managing to keep a firm grip on the puppy
X Factor judge Tulisa Contostavlos proved she's as tough as she acts today when she kept a firm hold on her pet rottweiler.
The north-London born singer, 23, held tight on the dog's lead as she paid a visit to the contestants from her group at the house they share.
Tulisa's dog is still a young puppy, but they are bred to be strong and could easily have dragged the pint-sized singer to the ground.

However, she kept the pooch under control and kept her cool as she walked the eager dog into the house.
She wore a cute bright yellow babydoll dress and sparkling flip flops for the visit.
Her appearance came as news broke that one of her groups could face legal action over their stage name.

Under fire: A charity is threatening Rhythmix with legal action over their name
A charity bearing the same name as Rhythmix is seeking legal advice after its name was adopted by X Factor band.
The manufactured girl group made it through to the live shows after their mentor Tulisa put them in her final four at the judges' houses.
But now the name the girls chose for their band at boot camp is being contested by a leading music charity which shares the same name.

In a statement, Rhythmix the charity confirmed it was registered with the Charity Commission under the same name - which it has trademarked.
The statement continued: 'We are aware of the use of the trademarked name of 'Rhythmix' by the X Factor.
'We wish to make it clear that there is no connection between the charity and the television show or the band.

'There is no connection between any usage by the programme of the word Rhythmix and the work of the charity or any agreement by the charity to permit such usage.
'We are currently in discussion with legal representation to resolve this matter.'
Elsewhere, Tulisa has defended the X Factor featuring hopefuls as young as 16 on the show - and said rejection helped to toughen them up.
