LANCE ARMSTRONG ON EX. SHERYL CROW

Sheryl Crow's ex-boyfriend Lance Armstrong has vowed never to discuss his private life in public after his high-profile relationship with the rocker ended last year. Armstrong, who split with the singer last February, believes speaking out about potential partners puts "unnecessary and unrealistic expectations" on a couple -- and he intends to stay silent over any future love conquests. The 35-year-old cyclist says, "We are not going to talk about whoever is involved or whoever is in my life. If somebody takes a picture they can put two and two together. "It's so hard. It puts too much strain and unrealistic expectations on a relationship when you put it out there. "It's tough when you love somebody and you want to be with them, you want to talk about them. It's not easy, but I think it is by and large better not to talk about it."
