Sara Leal has finally broken her silence about what she alleges went on in Ashton's San Diego hotel room last month, and she doesn't hold back. Uh-oh.

From how Ashton made the first move, to how they got naked in the hot tub, Sara gives a full account of what she claims went down on the eve of Ashton and Demi's six-year anniversary.

So how did it all start, Sara? She told Us Weekly: "He just came up and kissed me."

What happened next?

Speaking about being nude in a hot tub on the balcony with Ashton and another woman, Sara said: "I didn't think it was out of the ordinary. I wasn't self-conscious about getting naked."

Apparently, Ashton told Sara he was "separated" from Demi.

When they eventually headed to Ashton's bedroom past 6 am, Sara says: "he lost his towel and I took my robe off."

"Then we had sex."

Oh dear.

Surely we don't want the details? Well, Sara's happy to give them to us: "He was good. It wasn't weird or perverted."

When it came to the post-coital talk, Ashton apparently waxed lyrical on politics, religion and astrology.

Sara also claimed Ashton didn't wear a condom.

Oh dear times two.
