Jessica Alba

Actress Jessica Alba has fuelled speculation that her relationship with long-term boyfriend Cash Warren is in trouble, after admitting she won't have children until she has found a "partner."

The 26-year-old has been dating film producer Warren since January 2005, but said in a recent interview she is still searching for the perfect father for her future children.

She tells In Style magazine, "I'm not the easiest person to hang with. I'm away a lot, and it's an unconventional life.

"But if I could find a partner, that would be best. I probably won't have kids without one.

"My parents taught me about unconditional love, because you have your ups and downs but you stick through it. I learned a lot from that, and I know that kind of love is possible.

"My parents made a forever commitment, and I know that's what I want."
