Clearly both are very much over their former romances with Richie Strahan and Sophie Monk, respectively.
TV's most unlikely duo were spotted tenderly kissing one another at Iluka beach in Northern NSW.
Sources have told Woman's Day exclusively that the Bachelor In Paradise co-stars might have another reason to celebrate.
Keira, 31, took the huge step of introducing the vineyard manager to her family at her mum's home near Yamba.
While they're yet to officially confirm it, friends believe the pair have all but gotten engaged – all that's left to do is to pick out Keira's dream ring!
Jarrod, 31, and Keira certainly looked like they were celebrating when they hit the beach.
As our exclusive pictures show, the duo could barely keep their hands off each other – with romantic Jarrod using any excuse to kiss his bride-to-be.
Onlookers spotted the lovebirds enjoying fish and chips by the water, before taking a dip in the sea with Keira's pet pooch Romeo.
"They were all over each other," one source observed.
"They weren't bothered if anybody could see them. But it was all very natural."
Adding, "They looked like a cute couple in the first stages of a romance."
Now Jarrod has Keira's family's seal of approval, friends think it's only a matter of time before they walk down the aisle, especially given Keira's long-time desire to settle down.
"Keira's always wanted a husband and kids," a friend told us.
"That's the whole reason she signed up for the show."
Meanwhile, those closest to Jarrod say he's completely smitten.
In fact, he thinks Keira is The One.
"He said they have an amazing connection" said an insider.
"She's been a little more guarded about her feelings, but is constantly by his side."
Adding, "It's looking to be one of the great Bachelor romances."
There's no doubt Jarrod, who was engaged once before – in 2010 for six months – would pull out all the stops for the wedding.
He's already spoken of his dream to marry at his family's vineyard in Gippsland, Victoria.
"When I proposed [the first time] I was too nervous to ask, so I wrote my words in the sand and knelt alongside it," he told Woman's Day.
