But this is not the first time that Jennifer has suffered from grief.
Jennifer, 36, and Greg started dating soon after being abandoned over Christmas 2012 by her former Dancing On Ice partner Sylvain Longchambon.
Sylvain would have called her on Christmas day to tell her that he had feelings for his new TV partner Samia Ghadie.
A devastated Jennifer was humiliated when Sylvain ended their two-year relationship.
After Sylvain’s bombshell, she told him to leave their house, saying, “I want you out – now.
Beauty Hollyoaks, 29, told Sylvain to pack his bags after admitting to having “feelings” for his new skating partner.
She then texted him asking him to leave their home near Liverpool on his return from a trip to France.
But just 20 days after the split, she and Greg were seen together and they were also seen with her parents.
But she was hit with more heartache in 2012 when she parted ways with her rebound man after just four months, according to her pals.
At the time, her friends told the Mirror that she “wasn’t ready” for another relationship.
One said: “Jen and Greg have always been doomed – she’s not really about everything that happened with Sylvain.
“She’s a lovely girl and deserves to be happy, especially after everything she’s been through with Sylvain, which was really humiliating for her. But it doesn’t seem like Greg is right for her.
“They knew each other anyway, but started spending more time together. ”
The couple managed to fix things up and get back together.
They welcomed her son Daye into the world in June 2017, with Jen describing him as her ‘miracle baby’.
In 2018, when asked if she was still in contact with Sylvain, Jennifer admitted that she had not had any contact with him.
Jennifer told Express.co.uk when asked if she was still in contact with Sylvain: “No, no. ”
Last month, she paraded her stuff in steamy bikini photos during the heatwave – but Greg was nowhere to be found.
After her split with Greg, she wrote on Instagram: “Greg and I decided to go their separate ways a few months ago. We remain friends and we will both continue to co-parent happily Daye and would appreciate privacy during these times.
“Thank you to everyone who supported us before, during and after this. ”
The most recent photo of Jen and Greg together on her Instagram page is from July 12, and it is not known if they had separated at this point.
She shared a series of adorable family snaps from their day at the park with Daye, captioning them: “Having fun in the sun.”
Greg, who appeared on the MTV show’s first series alongside Vicky Pattison, Gary Beadle and Charlotte Crosby, shared a very similar statement on his own Instagram page.
He also still has pictures of Jen on his account, proving that they remain close despite their breakup.
