'Dancing with the Stars' Live Finale On High Alert

EXCLUSIVE

"Dancing with the Stars" producers are doing everything they can to avoid an encore performance from protesters ahead of Tuesday night's season finale.

Cops and K9 units lined the check-in area Tuesday afternoon at The Grove in L.A. where they're shooting the finale. We're told security is on high alert due to the anti-Ryan Lochte protesters who stormed the dance floor in September. A criminal court hearing for those 2 guys has been delayed until next month.

Lochte is out of the competition, but he'll still be in the audience tonight. Sources tell us producers are also concerned about new protesters in the current political climate.

That mirror ball trophy is serious biz.
