Speaking to the Irish Independent, the 35-year-old admitted that she and husband Daithi O Caoimh had yet to enjoy a honeymoon and that they have barely had time to see each other since their wedding in September.
Caroline and Daithi tied the knot in Tuscany, Italy.
They enjoyed a three-day celebration in the small town of Monteriggioni, with 110 guests.
"He and I have not had a huge amount of time together this year because I've been away a lot. It is difficult, but that's what I signed up for with acting – you have to go where the work is," the former 'Off The Rails' host said.
The pair are based in Los Angeles, with Daithi quitting his finance job in Dublin to join Caroline after she moved to pursue an acting career.
While it's "ferociously competitive", Caroline insisted that she wasn't ready to give up on her Hollywood dream.
"It's completely daunting because over in LA there are opportunities everywhere, but there are 10,000 people touching down in LAX every day with the same goal," Caroline said.
"I've a project that I'm due to start shooting in January, but who knows? Things can happen."
Caroline was on hand yesterday to launch Focus Ireland's text donation line, ahead of the housing and homeless charity's annual fundraising 'Key to a Home' weekend.
While back in Ireland, she will attend the premiere of her latest movie 'I Can't See You Anymore', which features in the Cork Film Festival this weekend. She stars alongside David Murray.
"It's the first Irish role I've had in a while and the first proper, meaty one... I'm very excited about it," she said.
