Samantha Ronson has become a constant figure in Lindsay Lohan's life, and now the DJ is even influencing her fashion.

The actress stepped with her lover in New York last night wearing a T-shirt decorated with a silhouette of a woman that looked just like Sam, complete with trilby hat and cigarette.

It was topped with the French term for love - 'j'adore'.

Sam returned the favour the following day, wearing a jacket with 'I Love You' emblazoned across the back.

Sources say the pair are becoming increasingly comfortable with taking their romance public.

An insider tels American magazine People: 'Sam is constantly on the set of Labor Pains. They're very affectionate.'

'Lindsay is so happy now because of Sam.'

Sam, the sister of music producer Mark Ronson, has also won the approval of Lindsay's mother Dina.

She says: 'I love Samantha.'

'She's like a child to me. They're great friends and as long as my daughter is happy and healthy, it is what it is.'
