Beckinsale cautious about having more kids

Kate Beckinsale doesn't know if she wants more children.

The 38-year-old actress' husband Len Wiseman is keen on the idea of them having a baby together but the 'Underworld' star – who already has 12-year-old daughter Lily with ex-partner Michael Sheen – is cautious having seen friends go through the "tragedy" of miscarriage.
