Lindsay Lohan and Samantha Ronson's reported romance has received its blessing from the DJ's music producer brother Mark - who "approves" of their relationship.

The pair has yet to confirm their rumored lesbian romance, despite being seen kissing in public.

Ronson has previously announced that the pair make a cute couple and now his girlfriend, model Daisy Lowe, has confirmed that the relationship is genuine.

She tells British newspaper the Daily Mirror, "Her (Lindsay) 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."
