Feds are worried that  former beauty queen Miss Iceland 1974 who tipped cops to location of missing mob moss may be marked for death.

On-the-run mob boss James “Whitey” Bulger was turned in to the FBI by his neighbor, a former beauty queen, who collected the $2 million reward for the tip that lead to his arrest.

Anna Bjornsdottir, a former Miss Iceland 1974 and a model and actress best known for her Noxzema and Vidal Sassoon commericals, lived in the same apartment complex as Whitey and his fugitive gal pal Catherine Greig. 

Ann befriendedthe fugitive couple when she and Catherine took care of a stray cat together.

The beauty queen was vacationing in Reykjavik earlier in 2011 when she saw a news report about Bulger on the FBI’s Most Wanted List and contacted the authorities about her neighbor.

Bulger and Greig were arrested in the apartment in June, where they had hidden $822,000 in cash in the walls and had about 30 guns, grenades and other weapons.

The FBI said they paid $2.1 million in rewards to “more than one individual” but the Boston Globe reported $2 million of that was paid off to Anna who may now be targeted by mob pals of Whitey’s for a revenge driven hit.

Bulger, the former mobster, who was the inspiration for Jack Nicholson’s character in “The Departed”, is facing charges on 19 murders. He has plead not guilty, reported.
