The reality stars had dated when they were younger and came face to face once again on TOWIE when Lewis surprised Sam by joining the show.
There was no romance on the cards second time round, however.
Speaking ahead of the new series of TOWIE starting, Lewis said: "I regret losing Sam. She was the first girl I loved and I think I always will. I'm glad she's happy and in a good place – she deserves it."
Sam is currently dating businessman Paul Day and enjoying success away from TOWIE after leaving the show.
In her recent autobiography, Secrets & Lies, she speaks about her romance with Lewis, saying "we were loved up and had a good thing going" until he cheated on her.
She admitted she was "surprised" when Lewis joined the show, saying: "Lewis thought he could just stride back into my life and pick up where we left off, despite the fact that he had cheated on me so close to home."
TOWIE starts Sunday, 14 June at 10pm on ITVBe.
