The two stars were spotted mingling with one another and their Essex pals at James 'Arg' Argent's food party on Sunday (9 March), where they were shooting scenes for tonight's episode of TOWIE (12 March).
Getting into the spirit of the bash, Lewis decided go for gold with his outfit and dressed as a giant pineapple - complete with elaborate feather headpiece!
He would fit right in at a carnival!
But undeterred by his amusing costume, Lewis still felt confident enough to speak to newbie Grace, who was dressed in a glamorous black fringed top and a yellow miniskirt.
Clearly she wasn't keen on taking part in the food theme.
The reality TV pair have been seen flirting throughout the latest series of TOWIE, although Grace initially ditched Lewis to go on a date with Italian stallion Mario Falcone.
But since Mario has now taken a vow of celibacy, it seems Grace is willing to give Lewis a fair shot.
And we can already imagine he will make more progress with the brunette beauty than Mario did!
Also at the party over the weekend was Lewis' ex-girlfriend Sam Faiers and her pregnant sister Billie, who chose to dress up in kimonos with friend Ferne McCann.
Meanwhile, host for the night Arg truly embraced the food theme by donning a giant pizza costume.
He was later caught on video rapping by Lauren Pope!
TOWIE continues on ITV2 tonight at 10pm.
