Liv Tyler (Arwen) will be on 'The Tonight Show with Jay Leno' on Thursday, October 7th. No doubt she is promoting her latest film Plunkett & MaCleane.

Liv plays Lady Rebecca, who is 'beautiful and rebellious' according to the tedious and totally out of place film website (sorry, 210 in the am!).

Be sure to check it out!

Tonight Show: 11:30pm ET NBC
