Madonna's headstrong daughter Lourdes may only be 14 but is already following in mum's footsteps.

The 14-year-old is said to have a new boyfriend called Carlo, who has a similar name to her dad, Carlos Leon.

She is also working on a clothing range with her mum, and the mother-daughter duo are teaming up with MG Icon for the collection.

A source said to UK magazine Now: 'Despite being so young, she's a girl who knows exactly what she wants and how to get it.

'She doesn't seem to be struck with much of the teenage angst that other children go through at her age - she's very self-confident and quite mature.'

The source added: 'She's only 14, but has her sights set on becoming a clothes designer. She doesn't care if people think she's too young. She just goes for it.

'She has her own ideas and vision and she's creative. And she expects a lot from her future.'
