SHE played the supportive other half last year when Ryan Tubridy covered Graham Norton at the BBC, but it looks like Aoibhinn Ni Shuilleabhain will be too busy to accompany the Late Late Show host this time.
With her PhD in mathematics and filming for her new telly show Science Squad keeping her busy, the teacher has yet to determine whether she'll join Tubs in London next month.
The 38-year-old broadcaster is set to fly over to the UK to kick off his first stint filling in for Chris Evans on BBC radio over the June bank holiday weekend.
But for on/off girlfriend Aoibhinn, it'll be a case of checking her schedule.
"I'm not sure yet, I'll have to look at my diary," said the brunette beauty.
"I have a holiday planned but it'll be quite busy for the next few months, I'll be working the majority of the way through."
Speaking at the Intel exhibition at Trinity College's Science Gallery, the 27-year-old admitted that she may be forced to miss out on attending this year's Rose of Tralee, thanks to her work commitments.
"Unfortunately I don't know yet because it could clash with the Fleadh Ceoil. I'll find out in the next few weeks hopefully. I can't believe it's been seven years since it was me down in Tralee."
The bubbly personality has been announced as part of RTE's summer schedule line-up and will see her brand new series kick off on June 14.
"I'll be nervous about the reviews, I just hope people tune in and enjoy it. This is a really good time for science to be on television. I hope that people like it and find it exciting and it'll spark a bit of interest, because when they hear it's a science show people wonder what it'll be, whether it'll be for adults or for young people."
Aoibhinn will share the spotlight with Jonathan McCrea and Kathriona Devereux on the upcoming series.
"We've been filming it since February so it's been a prolonged thing, I'm really looking forward to seeing the finished product now."
