The reality stars arrived for a personal appearance at Mayhem Nightclub in Southend-on-Sea on Friday night, where they partied into the early hours of Saturday morning (30 March).
Posting two photos on Twitter from the club night called 'Reality Wars', Lewis said: "Got loose last night @JamieLaing_UK #mayhem #MIC #TOWIE."
In one snap, the two lads were all smiles as they posed for a photo, while another shows Jamie planting a kiss on Lewis' cheek - is this a new bromance?!
While Lewis has just wrapped up filming for TOWIE's eleventh series - which will conclude on Wednesday (2 April) - Jamie is set to return to our screens on 7 April for MIC's eagerly-anticipated seventh series.
It was clearly a wild night for the boys though, as Lewis later tweeted: "Me and @BenDavison_ barely made it out of @MayhemNightclub alive. Cab home now can not wait for my bed!x."
