The star of the Three advert is in hot water.

Socks - the famous dancing pony from the Three advert - is at the heart of a DNA paternity probe.

Socks' owner Mari Williamson explains:

"I put him with three ladies in a field with a loch. But he is a very good swimmer and unfortunately he took a shine to another one of my mares – who I had put in a group with my other stallion Nuggett (pictured).

The distance across the loch didn't deter Socks.

"He just fancied her (Kimberley, pictured) more and thought the grass is always greener on the other side. Socks swam across – and with his three ladies in tow – and now we don’t know for sure who is Scamp’s real father", Williamson continued.
