Wedding bells for Zara Phillips?

Zara Phillips could become the first Royal WAG.

Speculation is growing that the Queen's grand-daughter will soon set a wedding date with her rugby star boyfriend Mike Tindall.

She watched her fiance play for England against Scotland at Twickenham on Saturday amid growing speculation about their relationship.

Zara, 28, has so far kept her cards close to her chest with regard to a wedding, but friends of the couple say they are searching for a suitable date and may marry this year.

The couple live on the Gatcombe estate, near Minchinhampton.
