A man allegedly obsessed with Shawn Johnson was arrested early Tuesday morning.

He was trying to sneak onto the "Dancing With the Stars" set and, according to TMZ, cops say he had a loaded shotgun and .45,  zip ties and duct tape in his car.

The contestant’s mother, Teri, has filed a petition for a restraining order against the man, Robert O’Ryan, 34. The restraining order seeks protection for 17-year-old Shawn, her mom, dad and "Dancing" partner Mark Ballas.

According to documents, the LAPD searched the suspect’s car, finding both a loaded .45-caliber handgun and shotgun and materials including duct tape, zip ties and a map. Also found: "love letters, clippings and other information on the victim."

O’Ryan reportedly told police that "he had packed all his belongings and permanently left Florida to drive out here to be with [Shawn Johnson], he believes that she speaks to him personally through the television set and through ESP and that they will have a child together." He also stated that he "would be with her no matter what."

According to CBS’ report on the incident, the nightmare started Monday afternoon when a CBS employee saw O’Ryan jumping a fence and entering an East Studio hallway.

Security asked for ID. O’Ryan showed them an expired concealed weapons license. When guards asked whether he had a weapon, O’Ryan told them he had two guns in his car. At that point, the guards called the cops.

Johnson petition claims she’s "in fear for her life, she is extremely upset by this incident and her entire family and those around are all extremely concerned and fearful that [O’Ryan] might try to kidnap her or harm her in an effort to make good on his statements."

O’Ryan is in custody, booked on suspicion of carrying a loaded firearm in public, and is being held on $35,000 bail.

How scary is this?

All these injuries and now this apparent close-call kidnapping — or worse — attempt? Maybe "DWTS" really IS cursed.
