Earlier this month, the powers that be at Calvin Klein gave us a sneak peek at Zoe Saldana's debut as the face (and body) of Calvin Klein Underwear. And now, they're giving us even more to salivate over.

In this trio of just-released images from the Fall 2010 line, Saldana wears Calvin Klein's Envy bra, which is part of the company's new Coverage Level System offering female costumers three levels of coverage depending on preference and bust size.

In the Saldana ads, shot by Mikael Jansson in New York, the "Avatar" star wears different styles of bras from the Envy collection, the skimpiest of the three coverage levels, which makes sense given her smaller bust size and the fact that the more flesh we see of Saldana's, the better sales are gong to be for CK overall.

The other two levels of coverage are dubbed Perfectly Fit, which provides mid-level coverage, and Seductive Comfort, which offers the highest level of coverage and support due to a larger cup, as well as thicker straps and band.

If you think these ads are hot, wait until mid-August when Calvin Klein releases a sexy video of Saldana talking about the envy-inducing underwear.

In the meantime, check out Calvin Klein's racy video promoting the new X Underwear for men.
