The reality star – who romanced Sam way back before they were famous – told MailOnline that news of former TOWIE stars Sam and Joey parting ways again last week hadn't come out of the blue to him.
"I'm not shocked that they split. I used to hear a lot of things about their relationship," he said.
Referring to allegations that Joey told the media about their split without Sam knowing, Lewis said: "I was shocked when I heard [the allegations] that Joey dumped Sam through the papers though. But I know him and he is not a nasty person."
He added of himself: "If I was going to break up with someone, I wouldn't do it by telling the press. I would talk to that person face to face or over the phone."
Lewis, 24, is currently dating his TOWIE co-star Lauren Pope, 31.
It's been claimed that Joey and Sam were on holiday in Marbella celebrating Sam's sister Billie's engagement when the split happened. Sources claim Joey flew home to the UK alone.
Neither Sam nor Joey has publicly commented.
Sam, however, appears to not be letting rumours about her private life get her down, positing positive messages on Twitter and, last night, enjoying a glamorous night out in London.
