SNEAK PEEK: Taylor Lautner Strips Down for New Eclipse Trailer

The wait is almost over, Eclipse fans.

A 10-second teaser trailer for the third installment of the Twilight franchise -- due June 30 -- hit the Web Wednesday, two days before its full version premieres.

In the clip (watch above), Taylor Lautner strips down while professing his love for Bella (Kristen Stewart).

As Robert Pattinson's Edward urges Bella to consider the consequences of the choice she's making to romance Jacob, the werewolf puts himself on the line for his new love.

"I'm going to fight for you until your heart stops beating," Jacob tells Bella in an ethereal scene that ends just before the two go in for a kiss.

The full Eclipse trailer will premiere in theaters nationwide before Pattinson's Remember Me, starting March 12.
