The TV star emphasised her tiny waist in a black lace top and red skirt combo, which she teamed with pretty flowers in her updo.
Lucy was seen flirting with Dan as they filmed the latest scenes for the ITV2 reality show - just a week after the pair ended their relationship after he discovered he's going to be a dad.
The scenes, filmed at Elms Farm, West Hanningfield, also see Dan reading an 'idiot's guide' to being a dad and sharing his fears with his friends.
During the summer day trip, Ferne McCann and Charlie Sims showed their love for each other with a cuddle, while Charlie King, Chris Drake and Bobby Norris relaxed over drinkies.
Meanwhile, Sam Faiers and Joey Essex look happy - but not together - as they try to avoid each other during the scenes.
Joey can be seen fooling around with pals James 'Arg' Argent and Tom Pearce and blowing bubbles, while Sam, sister Billie and Gemma Collins danced around a maypole.
Sam and Billie channelled their inner hippies in floaty white gowns and floral headdresses as they filmed the garden scenes at the farm.
With all this rain at the moment, the stars were lucky the sun decided to shine on them!
