Tori and Dean hosted a pool party this weekend – not at the Spelling McDermott home – but at a Las Vegas casino!

Tori Spelling did it up in a two string tiny bikini as she and hubby Dean McDermott hosted Palazzo Las Vegas’ pool party this weekend. The event was Saturday at the Azure pool inside the stunning Vegas resort.

But don’t just think it was a mom and dad affair – along for the ride that weekend were kids Liam and Stella. The couple at the pool brought out one other surprise – Tori’s current book Mommywood – which Spelling signed copies for pool side guests.
