Casa Amor is back for 2021 and 12 new contestants have joined the show.

Monday night's instalment of Love Island saw the boys sneak out of the main villa to meet six new bombshells, Salma, Lillie, Amy, Clarisse, Mary and Kaila, while the girls went about making sure they wouldn't forget about them during their stint away.

Millie Court, who has been coupled up with Merthyr-born Liam Reardon since her late arrival, took off a signature piece of jewellery she's been wearing throughout the series and packed it in the 21-year-old's suitcase.

"I swear to god if he loses this Sagittarius necklace I'm going to go mad," she told her fellow islanders.

But while the girls settled down to a game of 'never have I ever' with the new male contestants, the boys in Casa Amor played truth or dare, which resulted in Liam kissing two of the new girls as part of the challenge.

Many fans were not happy that Liam had joined in, especially after Millie's sweet gesture.

Millie's Sagittarius necklace has Love Island viewers all saying the same thing

"If Liam doesn't understand the weight of that Sagittarius necklace," wrote one.

While another added: "Liam… She gave you her Sagittarius necklace. SHE GAVE YOU HER SAGITTARIUS NECKLACE!!!!!"

And a third said: "Millie looks so empty without her signature gold Sagittarius necklace. She really sacrificed the finishing touch for all her outfits giving it to Liam. He better appreciate her and stay loyal."

"If Liam walks back into the villa with anything other than the Sagittarius necklace I swear," typed a fourth.

Others were desperate to get their hands on the sacred gold Sagittarius chain. So where's it from?

While Millie's exact necklace hasn't been confirmed, there are plenty of places selling gorgeous star sign jewellery.

Rock n Rose have a Sagittarius Zodiac Nameplate Necklace for £29. The delicate gold plated necklace has a solid brass base and features a Sagittarius script nameplate.

Meanwhile, Wolf & Badger have a Sagittarius 22Ct Gold Vermeil Zodiac Star Sign Necklace on offer for a slightly more expensive price of £68.

Love Island's official partner I Saw it First is also selling a Gold Sagittarius Star Sign Necklace which is priced at just £5.40 in the sale, but it's currently out of stock so you'll have to keep an eye on it.

Love Island continues tonight at 9pm on ITV2.
