She told Red magazine:"I can't wait to be a wife. It just feels really solid.
"I want to have the same surname. I want to feel like we've done it properly."

The couple first met in 2011 when the DJ, now 32, was supposedly on a girls' getaway in Ibiza with a group of friends including Denise van Outen. They quickly became inseparable.
It's obvious what the attraction is. The bubbly presenter appears part rock chick, part homebody – just like the women Jesse has grown up around such as his stepmother Jo Wood, Ronnie's second wife.
His own mother was ethereal Sixties beauty Krissy Findlay, who died in 2005, aged 57 of an accidental overdose.
Fearne describes her man, who is five years older than her and an accomplished guitarist, as "the nicest guy in the world".

The blonde has put her hectic socialising behind her since the relationship begun. Fearne loves being mother to the couple's son Rex, who was born on 21 February, 2013, and stepmother to the children of his first marriage Lola, eight, and Arthur, 12. These days she's mostly likely to be found baking or filling the washing machine.
At Christmas, the duo announced their engagement, with Fearne proudly showing off a unique sparkler. Their families were also excited with Leah, Jesse's half sister tweeting about the happy news.
The pretty DJ has also been embraced by Ronnie and his second wife Sally, making her part of the sprawling rock clan even before the proposal.
Fearne was previously engaged to a skateboarder called Jesse Jenkins, but called it off in 2011.
In an interview with Cosmopolitan, she said of that time: "What you don't know at the time is that as one door closes, another opens - and, soon after, I met the love of my life and got to have a baby.
"Jesse and I met through a friend in a restaurant in Ibiza and we just clicked... I don't think there's anything you can really pinpoint when it happens like that. I'd been in love before, but this was different. He makes me laugh, and he balances me out.
"He makes me laugh all the time and he's so chilled out. He's been to hell and back in certain ways, so nothing fazes him; he takes it all with a pinch of salt."
