LUCY Mecklenburgh and Ryan Thomas hosted a glamorous engagement party that could have been mistaken for their wedding in London on Friday night.
The celebrity couple spared no expense as they celebrated on the River Thames near Tower Bridge and invited a string of famous pals and close family to the bash.
Lucy, 27, has given her 1.4million Instagram followers an inside look and shared snaps on social media of her preparations in a nearby hotel.
She sat as a team of professionals worked on her hair and make-up and later, filmed the couple's journey to the party on a boat in central London.
Ryan, 35, and Lucy grinned and pointed at her gorgeous sparkling ring, showing off a glimpse of her sequin dress that featured a tight corset and layers of billowing white material.
Later, the ex-Towie star and her pals filmed inside the incredible celebrations.
Inside the entrance to the glittering bash were huge letters in lights spelling out 'LOVE' and dozens of colourful balloons, adorned with bunches of fresh flowers.
The room had been set up to include a dance floor, and space for a DJ as well as a stage for a band.
Guests, including heavily pregnant Brooke Vincent and Ryan's brothers Scott and Adam, cheered as Ryan twirled Lucy around for a romantic first dance.
Hungry guests were served Italian Gelato ice cream and slices of an impressive six-tier cake.
Afterwards, the party gathered around a large screen and watched a sweet video montage of recorded messages from the couple's loved ones, as well as a clip of Ryan proposing to the stunner in Italy last month.
Just weeks ago Lucy revealed how her actor beau, 35, popped the question at the lavish Villa Treville Positano.
The reality star first wrote: "So this is what happened last night..."
She then shared a short video of her and Ryan boarding a private boat to the five-star hotel while taking in the Amalfi Coast's beautiful scenery.
Wearing a lace ruffled maxi dress, Lucy complemented the garment with a pair of strappy black heels and a statement headband as she sauntered to their private candlelit dinner.
The brunette beauty was blown away by the romantic setting, which featured a single white table and two chairs perched on secluded grass terrace surrounded by rose petals and overlooking the incredible view.
Lucy captured the moment she saw the setting on her social media and looked spellbound by the scenery, captioning the video: "I still had no idea!!!"
The candid clip come hours after she shared the moment Ryan popped the question in the picturesque Italian resort of Positano.
She wrote: "I said YES" along with a ring emoji.

She then took to her Instagram Stories to share a closer up shot of her new bling, which Andrew Brown, CEO of WP Diamonds, believes is a four carat yellow diamond ring worth £60,000 to £70,000.
The couple met on Bear Grylls' show Celebrity Island in 2017, going public with their romance a few months later.
At the end of last year, fans feared that the celeb pair had split after Lucy was filmed allegedly "kissing and holding hands" with another man.
