Why Chelsie No Longer Has The Necklace Matt Agnew Gave Her On 'The Bachelor'

In one of their final dates on the show, Chelsie had to use a series of math related clues to break a combination on a safe.

The code for the safe was an equation, with each of the numbers symbolic of each one of their dates on 'The Bachelor' which Matt adorably dubbed 'the sum of us'.

Yes, Chelsie had to do math on a date to work it out. But she did find the whole situation 'quite cute'. It tapped into something they both have in common and tied in everything that they loved doing together during show.

When Chelsie cracked the code, she opened the safe to find a gift box inside containing a gold bar necklace with the formula for oxytocin -- the 'love chemical' -- engraved on it.

It had special meaning for the couple because when Chelsie met Matt, she gave him a temporary tattoo that was the chemical structure of oxytocin which she placed just above his heart.

Given it represented the beginning of their journey together, Matt gave her the necklace as a gift in return, so it would also be close to Chelsie's heart. It was so sweet it could bring a tear to your eye.

Yet speaking to 10 daily following the finale and the big reveal that Matt had chosen Chelsie, the Melbourne local said she hasn't been wearing the necklace because she currently doesn't have it in her possession.

"I had to hand it in just in case because I couldn't have been seen wearing it," she told 10 daily.

Given the high level of interest around 'The Bachelor' with the women usually being under intense public scrutiny as many try to speculate who Matt has chosen, it was deemed too risky for Chelsie to wear it in public.

Well played, very well played.

Yet Chelsie said as soon as it's returned to her, she will definitely begin wearing it again. "I will get to have it back, I'll be wearing it once I do," she said.
