American singer Britney Spears and her boyfriend Jason Trawick have made quite a few steamy scenes together, for the music video of Spears' latest song, Criminal. Spears' decision to cast her boyfriend was a smart one, vouches Chris Marrs Piliero, the music video director.

When you're doing nudity, I don't think it was at the top of Britney's list to bring in some random guy while her boyfriend watches, Piliero told USA Today, She wanted to kind of have this fairy-tale, sweet, knight-in-shining-armor feel to it. I said let's take that and make the fairy tale badass.

We definitely wanted to make some passionate, steamy scenes, but we also wanted it to be intensely beautiful. We didn't want to go for raunchy. We wanted it to be sensual and steamy, Piliero added.

Piliero admitted that he wasn't exactly sure of Trawick's acting abilities when they began the two-day shoot. However, Trawick didn't disappoint either his lady love or the director and did amazingly well for a first time actor.

The cool thing was I didn't have to try that hard with (Trawick). He came with his game face on. He was open to whatever direction I gave him and he delivered it. While this isn't some extravagant role, you believe him, said Piliero.

Trawick reportedly went on a crash diet, losing between 40 and 60 pounds in a matter of weeks before appearing nude with his pop star girlfriend for the video.

The official video is now available on Britney Spears' YouTube channel and has crossed 1.5 million views within six days.
