The trio were pictured today (19 July) while enjoying the sunshine at Bluebird Cafe, a swanky eatery on the Kings Road in Chelsea, London - Spencer's stomping ground.
Earlier this month, it was revealed that Stephanie had started dating Spencer after meeting him through his celebrity pals.
It appears the couple were enjoying a lunch together when they bumped into Lucy, who was looking super glam in a rather extravagant pearl and jewel necklace.
Commenting on their meeting, Lucy tweeted: "Reality off! @SpencerGeorgeM @StephaniePratt #TOWIE #TheHills #MIC..."
Lucy then joked about Spencer's choice of attire, saying: "Yes Spencer that canary vest is very offensive."
Spencer also shared a group shot of himself with the girls, commenting: "Crayfish salad at Bluebird with ma giiiiirls... @stephaniepratt @lucy_meck .. #ThatSh*tCray."
