Viewers of the Essex-based reality show were introduced to Olivia on yesterday's episode after Lewis' boxing match against Elliott Wright.
Dressed in a glamorous red dress, she was seen hugging Lewis following his defeat to Elliott, and admitting it had been horrible watching him in the ring.
But when Jessica Wright asked if she and Lewis were dating, Lewis remained very coy, saying only: "She's special to me."
They did then leave the after party early holding hands. Hmmm…
And just to keep us guessing even more, Lewis tweeted last night: "The biggest knock out of the knight… @OliviaAmoroso #TOWIE (sic)."
(If you didn't watch the episode, poor Lewis was knocked out by Elliott within the first 30 seconds of the fight, but did try to get back up again, earning him plenty of respect from the Essex boys.)
Olivia replied: "Hahaha ur spelling! And to think we went to a private school (sic)."
But while Lewis and Olivia were clearly in good spirits last night, there was one person not so happy about it all: TOWIE newcomer Grace Andrews.
Grace and Lewis had been flirting on recent episodes of the show, with Lewis even leaving flowers on Grace's car in a romantic courtship gesture. But on Sunday night's episode, it all went downhill and Grace was left in tears after being given the cold shoulder by Lewis.
She told pal Georgia that she felt "mugged off" and then last night, we saw her looking pretty upset when Lewis and Olivia left the boxing party holding hands – right in front of her.
Grace had also told Georgia she heard rumours Lewis was back in touch with his ex-girlfriend.
Earlier in the night, Grace had chatted with Sam Faiers, who went out with Lewis when she was just a teenager. "I've seen a side to Lewis that I never thought I'd see. Literally within a second he's gone from being one person to another," said Grace.
Sam replied: "He can either be the life or soul of the party, a gem, lovely, or this miserable, moody, angry… I don't think he's going to change. Why is he acting like this? He was so into you sending you flowers. It's almost like there is something else. It can't just be the boxing."
Meanwhile, Grace hasn't commented on last night's episode via Twitter, apart from saying: "Ahhh thank you everyone for such lovely comments! Love you all."
Ooh, we can't wait for the next episode!
