Duchess Catherine is taking horseriding lessons even though she is allergic.

The royal's husband Prince William would love nothing more than for his spouse to share his love of horses so Catherine - who was known as Kate Middleton before her marriage - has decided to take lessons, even though it is uncomfortable for her to be around them.

A source said: ''William has always wanted her to ride with him. Horses are a big part of his life. He grew up watching his mother Princess Diana ride and he learned very young. He even had a pony of his own since before he could even ride.

''He would love to share his love of horses and horseback riding with Kate and she really wants to make him happy.''

Despite her allergies, Catherine is excited about the lessons.

The insider added to America's OK! magazine: ''She's really looking forward to being able to join in all the family activities that involve riding. She feels it's more than worth it to feel like part of the family.''
