Lindsay Lohan And Sam Ronson "A Lovely Couple" Says Brother's Girlfriend

Lindsay Lohan has been linked to DJ Samantha Ronson for months, and now Sam's brother's girlfriend has gone on the record about the pair's relationship. Photos over the past few months have shown Lohan and Ronson in constant company, holding hands and kissing.

Now, the girlfriend of Sam's brother Mark (Grammy-winning producer of acts like Amy Winehouse) has spoken to a British paper. Model Daisy Lowe, who has been dating Mark for about three months, told the Mirror:

"I met Lindsay and Sam for the first time during the weekend before the Coachella festival.

"Sam is an amazing girl. The four of us had a brilliant time - a real laugh."

And it seems that Daisy is also really taken with legendary party girl, Linds, 22. "Lindsay is really down to earth. Her and Sam make a lovely couple - they seem really happy.

"Their relationship is totally genuine. And they're just so sweet together.

"Mark totally approves. But we're not going to double-date again - I mean, would you go on a date with your brother? It's just a bit weird and anyway they live in LA, so it's kinda difficult.

"But I'd definitely love to see them again."

Lowe, 19, was recently revealed to be the daughter of Gavin Rossdale.
