Gibson linked to Russian singer

A Russian singer has apparently been spending time with Mel Gibson and recently holidayed with him in Costa Rica, People reports.

Oksana Grigorieva, 39, is signed to Gibson's label Icon Records and has also lived in a house linked to the actor.

The Passion Of The Christ star's wife filed for divorce this week, bringing to an end their 28-year marriage.

Sources said that Grigorieva, an ex-girlfriend of Timothy Dalton, stayed at a Californian home which was bought in December 2008 by an ownership trust administered by Gibson's company.

Former agent Victor Kruglov said that she rarely talked about her relationships, adding: "She was always very discreet about her personal business."
