Pippa Middleton And Nico Jackson Attend Friend's Wedding In Rural Scotland, But When Will They Get Engaged Themselves?

With engagement rumours rife for Pippa Middleton and boyfriend of 18 months, Nico Jackson, the pair put in another cosy appearance together this weekend, aptly for a friend's wedding.

Nico was Pippa's date at the nuptials of old friends Rowena Macrae and Julian Osborne, which took place in Perthshire, rural Scotland.

Though it wasn't quite a couple's outing for the duo, as Pippa's parents Carole and Michael also attended.

Rowena is an old friend of Pippa's from her gap year at cooking school The Grange in Frome, Somerset. Her and husband Julian are also in Kate and William, the Duke and Duchess of Cambridge's close-knit circle of friends. However, with the Royal Tour barely over we imagine jet-lack prevented them from seeing the pair tie the knot.

So, it was over to Pippa to take the royal style baton. The youngest Middleton sister opted for a tried and tested formula, pairing a silk trapeze dress coat in cream by Suzannah with olive green pumps and a matching clutch by Emmy London. As ever, a hat was a must, with Pippa opting for a co-ordinting beret style adorned with a single feather.

This only has us more curious for what Pippa would wear to her own wedding. Her and Nico were rumoured to be set to announce their engagement soon after the close of the Royal Tour, but no happy news has broken as yet. We've got our eyes fixed on Pippa's ring finger, though...
