There may still be speculation but Lindsay Lohan and Samantha Ronson are in no hurry to deny their close relationship, if these pictures are anything to go by.

Holding hands as they walked through the set of Lohan's latest film Labour Pains, the pair couldn't keep the smile off their faces.

Knowing the message the photos would send, they appeared to be relaxed, natural and delighted to see each other.

Due to Lindsay's filming commitments, they have been separated for the past few days and were obviously counting down the minutes until they were together again.

And in a message of support DJ Samantha, 30, exclusively played material from the actress's new album earlier this week at a gig in Las Vegas.

Her latest album, entitled 'Spirit in the Dark' features Neptunes producer Pharrell Williams, Snoop Dogg and Akon.

Listening in the crowd at the exclusive party were Shannon Elizabeth and Kelly Brook's on/off boyfriend Billy Zane.

Another move indicating they are more than just friends is the $22,000 commitment ring Ronson bought the 22-year-old for her birthday last week.

Whatever the nature of their relationship, they certainly seem to make each other happy.
