Mark Ronson's Girlfriend Outs His Sister

O.K., maybe we can't call it "outing" since everyone already knows and for some mysterious reason can't quite declare it as fact, but producer Mark Ronson's girlfriend told the U.K.'s Mirror that his younger sister, Samantha Ronson, and Lindsay Lohan are in fact a couple.

According to various tabloid reports, Daisy Lowe, 19, Gavin Rossdale's daughter from his first marriage to singer turned fashion designer Pearl Lowe, and Mr. Ronson have been dating for a couple of months.

"Sam is an amazing girl. The four of us had a brilliant time—a real laugh," Ms. Lowe told the paper. "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."

She went on to say something about how she'd like to see them again, but they live in L.A., blah, blah. ...

We admit, it's a stretch to confirm their relationship through Ms. Lohan's girlfriend's older brother's girlfrend—huh?—but at this point we'll take it.
