The former Hear'Say singer jetted off with former WAGs Nicola T and Elen Rivas and ex-'Emmerdale' and 'Hollyoaks' star Sheree Murphy.
Kym was seen lazing around the pool with her gal pals in a pink two-piece, which revealed her killer curves.
The couple will be forced to spend five days a week apart, as Kym's on-going role as Michelle Connor in 'Coronation Street' means she will continue to be based in Manchester, while Jamie will be filming 'EastEnders' in London.
A source told The Mirror that it could spell trouble for their relationship, which already came under strain when Jamie unsuccessfully tried to crack America.
"It will often mean spending five days a week apart, and friends are saying that it’s only a matter of time before the cracks begin to show again," they said.
It was revealed last week that Jamie will be playing recovering alcoholic Jake Stone, who will embark upon an affair with troubled Lauren Branning, who has been facing her own battle with the booze.
"I have admired the show for many years... Jake Stone is a great character to play and I'm really looking forward to getting my teeth stuck into the role," Jamie said of joining the soap.
