Los Angeles- IT'S a good thing Beverly Johnson knows her way around a 9-iron.

Johnson, the world's first African-American supermodel-turned-wig tycoon, got a nasty scare yesterday morning when her jilted ex-boyfriend and a man-handling sidekick showed up at the Rancho Park Golf Club across the street from the 20th Century-Fox lot in Los Angeles.

We previously reported that Johnson had filed a restraining order against her one-time lover last week. Yesterday, she called police after being physically "attacked" by the ex's friend on the fairway and taunted by the man she briefly dated, who is described by friends as a "wannabe golf pro." Ironically, Johnson, who's also an author, is working on a new book titled, "Enough About Me, Let's Talk About Golf."

According to several friends of Johnson, the former catwalker had been on high-alert since receiving several "threatening letters" from the man last week, which she forwarded to Los Angeles Police Chief Bill Bratton at their urging.

"None of us even know his last name - we just call him the stalker-walker," says a close pal of Johnson. "He's a big guy and obviously very strange. None of us could figure out why she was with him. He tells everyone that he's a golf pro, but he's not. He just carries a bag everywhere. Pretty scary stuff."

We reached out to Johnson's best friend, Star Caps diet queen and gal-about-town Nikki Haskell, for her take on the episode. "Beverly wasn't hurt and is doing well, but she's obviously still quite shaken up," Haskell said. "She's been really worried for her safety, especially since she got those letters, and had been staying away from the golf course since she kicked him out of her house. Who does a thing like this?"

Sources say the boyfriend was arrested for violating the terms of his restraining order and that his slap-happy wingman was issued a citation.

An employee at Rancho Park confirmed late yesterday that an incident had occurred there and that police had arrested someone, but claimed he did not know the identities of those involved and said that management had left for the day.

Repeated calls to Johnson, her lawyer and the LAPD were not returned.
