Leo and Sienna?

Are Sienna Miller and Leonardo DiCaprio an item?

Seems so according to reports from NY.

Sienna famously split with Jude Law after the wanker cheated on her with the nanny and
Leo was dumped by Gisele for allegedly cheating on her for years and not wanting to settle down.
He likes models and she's as skinny as one.
They both seem frivolous and up for fun hanging out at Bungalow 8 after hours.
Seems like a perfect match.
