NFL standout Tim Tebow and former Vampire Diaries star Nina Dobrev are facing off tonight on Spike's Lip Sync Battle; find out where to watch it online.

Tebow and Dobrev are slated to do battle--Lip Sync Battle, that is--tonight on Spike. Throughout the week, the network has been hyping up this episode with preview clips. One features Tebow showing off his muscles and lip syncing to "Eye of the Tiger" by Survivor, while another shows Dobrev singing along to the always sexy "Let's Get It On" by Marvin Gaye.

Both competitors seem to be giving it their all, so it remains to be seen who will emerge victorious in the end. Thus far this season, the women have done better than the men--Tracee Ellis Ross defeated Anthony Anderson last week, Olivia Munn beat Kevin Hart the week before, and Channing and Jenna Dewan Tatum tied.
