Bride, 47, wants dress for her 21 year age gap groom with an unusual pet name

For most brides one of the most important thing is for them to be happy in their wedding dress.

But Vanessa is not most brides.

The 47-year-old is tying the knot with her toy boy groom, who at 26 is 21 years her junior.

And rather than finding a dress that she feels gorgeous in, she wants it to be all about him.

Vanessa is one of the brides searching for her perfect dress on TLC's Curvy Brides Boutique.

She said: "So normally the wedding is all about the bride.

"This time it's all about my groom. It's all about Nathan's day, it's his first wedding and I've been married before."

Expert Jo Cooke asks Vanessa exactly what the age gap is - and can't hide her shock when Vanessa explains that she's older than Nathan's mum.

Jo says: "I couldn't help my facial expressions and a little 'wow' popped out.

"I'm so sorry I didn't mean that, it was just there."

But the biggest shock comes when Vanessa reveals her pet name for her soon-to-be husband.

She explains: "They all call him the sex hamster."

After showing Jo and fellow expert, Alison Law, a snap of her groom, they agree.

They joke: "He's got beautiful brown eyes, he's got kind eyes... like a hamster."
