Fans of the show know Belle is in a relationship with Ellis Chapman, meanwhile Jamie is married to Andrea and they have a daughter called Millie together.
In last night's episode of the soap (December 13 2019), Belle found out Ellis was back from Dubai, however she was annoyed that he didn't tell her that he would be returning.
As it was the night of the vet's Christmas party, she tried to put Ellis to the back of her mind.
When she got to The Woolpack, she sat down with Vanessa and Jamie, where he complimented her appearance.
Later on, Belle started to feel down as she was reminded it was her first Christmas and birthday without her mum, Lisa, who passed away earlier this year.
She also ignored a call from Ellis, still clearly upset with him.
Viewers have picked up on the chemistry between the pair and some even think theywill cheat on their partners with each other - especially after the truth about Jamie's daughter, Millie, is revealed.
Something is definitely going to happen between Jamie & Belle #emmerdale

Although Jamie is married, it's not exactly solid. He and Andrea recently had an argument after she miscarried their baby.
She wanted to try for another but Jamie wasn't sure if he wanted another baby after the heartbreak of losing his unborn baby.
Meanwhile, Jamie's mum Kim knows Jamie may not be the father of Millie.
Andrea had a one-night stand with Graham Foster around the same time she began seeing Jamie.
Kim had a DNA test done, but after Andrea's miscarriage, she opted not to tell Jamie he may not be Millie's father as he had already lost one child.
But with Graham doing is own DNA test, will he reveal he could be Millie's dad?
Emmerdale airs weeknights at 7pm on ITV, with an extra episode at 8pm on Thursdays.
