Surprise Celeb BFFs!
Mel Gibson and Britney Spears
Recently separated from wife of 28 years, Robyn, Gibson has offered support to Spears -- and even invited her to vacation at his 400-acre ranch in Costa Rica. During the singer's much-publicized meltdown last year, Gibson -- who has helped people with sobriety issues over the years -- reached out to Spears. "[Britney]'s great," he has said of his pal. "She's a sweet girl."
