The reality TV stars found themselves tweeting about thunder (though we think they may have gotten thunder confused with lightening).
As torrential rain befell the streets of Chelsea, Lucy tweeted: ‘Ummmm why is there thunder.’
Mario then responded: ‘”Ummmm why is there thunder” I love it!’
Lucy (at this point confusing thunder with lightening) wrote back: ‘Doesn't it make you go blind if you look at it.’
Mario cheekily retorted: ‘Don't know! You check and let me know! If I don't hear back I will assume it does and you couldn't see your phone to reply ha.’
‘No you check!!’ Lucy replied. Mario gallantly put his eyesight on the line for the Made In Chelsea star as he ‘looked’ at the thunder… He wrote: ‘Tried... I keep blinking!’
Lucy revealed last year that she had the hots for TOWIE’s resident lothario, though ex-boyfriend Spencer Matthews reckons that a possible romance would be unlikely.
He told OK! last year: ‘Nothing bad to say about Mario, I don't really know him. But we're very different.’
‘Given that she was in love with me, I think it's far-fetched to think she'd feel the same about him,’ he added.
Mario was rumoured to be dating lingerie model Shelby Billingham following a secret romance with TOWIE co-star Chloe Sims.
