'I'm flattered, but it's all real', insists Vogue

The Howth woman, who got engaged to Spencer Matthews (28) last month, shared a throwback picture of herself taken at the Brown Thomas lingerie shoot, when she sported a curvier outline than usual.

Dressed in a skimpy red lace bodysuit, the 31-year-old showed off the results of all her hours spent in the gym for a rare modelling gig.

Surgical

However, it didn't take long for her followers to comment on her appearing fuller in the chest, with several fans asking if she had "got her boobs done?".

Laughing off any suggestions of having had any surgical help in achieving her figure, she replied to one commentator: "I must say I'm flattered, but no boob job for me.

"I've always been happy with them."

The same picture also featured a glimpse of her massive engagement ring from Spencer, estimated to be worth €170,000.

The ring was designed especially for the TV presenter and DJ by the former Made In Chelsea star, who popped the question in London at the end of last month.

The couple, who had just returned from a trip to Disneyland Paris, got engaged after a performance of musical The Lion King at the Lyceum Theatre.

Spencer said he knew Vogue was "the one" for a long time.

"We're very happy and in love," he said. "She's my best friend and I can't wait to spend the rest of my life with her.

"The engagement had to be special, and as our first trip away together was to Disneyland Paris, it felt like the perfect fit.

Romantic

"The Lion King is also one of the greatest stories of all time, so I figured that having just had a romantic evening watching it, she'd probably say yes."

The couple have enjoyed something of a whirlwind romance, given that they only met a year ago while filming Channel 4 skiing show The Jump.

Late last year saw them taking the plunge and buying a new place together in London's Battersea in a clear sign that their relationship was becoming more serious.
