Security will be very tight at Monday night’s “Dancing with the Stars” taping.

“They have ramped up security even through rehearsals and for the crew,” a source told Page Six.

The additional security measures come one week after hecklers rushed the stage during Ryan Lochte’s performance.

“It was very scary,” the insider, who was present during the fiasco, told us. “You didn’t know what was going on. Security handled it very poorly.”

This week, audience members can expect a lengthier process upon arriving to the Television City studio in Hollywood.

“This time they’re going to be patting people down,” the insider noted. “They’ve already sent out a memo saying come an extra hour early … They’re going to lock down the stage an hour ahead of time.”

Additional security was added over the weekend for rehearsals too, the spy also added.

A request for comment from ABC wasn’t immediately returned.
