A daughter of late presenter Gerry Ryan is to sing on the show her dad presented for one night.
Bonnie Ryan has recorded a single 'Love Me Now' that she will perform live on the Late Late Show tonight, and chat to host Ryan Tubridy.
Tubridy who turned 40 this week, was a close friend of Gerry Ryan, whose 2FM show he took over following the presenter's death three years ago.
Lottie, Bonnie's older sister, a showbiz reporter with slots on 2FM's Colm Hayes show, tweeted her excitement about her young sister's appearance:
"Rumor has it there's a great line-up for @RTELateLateshow tomorrow night @Bonnieryan1! #LoveMeNow"
20-year-old Bonnie is a budding singer and recently performed an intimate gig at Dublin's Grand Social.
Six years ago Bonnie performed as a support act to Westlife with her girl band Lady Nada at Dublin's Point Theatre, when she was just 14 years old.
Bonnie's siblings Lottie, Rex, Elliott and Babette and mum Morah all came out to support her gig in Dublin last week.
Footage from the night was posted by Bonnie on Youtube.
There is a long association between her dad Gerry Ryan and the Late Late Show.
Gerry made frequent appearances on the show over the years, including the infamous Lambo incident in 1987.
He presented the Late Late Show for one night in 2008, following the death of Pat Kenny's mother.
The late TV presenter made it known he would have liked to have taken over the show when Kenny stepped down, but wished his friend Ryan Tubridy every success when he landed the coveted role.
Tubridy hosted a special tribute to Gerry Ryan on the evening of his untimely death in April 2010.
And tonight Bonnie may catch the eye of another guest on the show, X Factor judge Louis Walsh.
However the student, who is studying music at Ballyfermot College has said she would prefer not to go down the talent TV shows route.
“I’m not really into competitions. Sometimes people go into them and they don’t come out as well as they hoped.
“I’d prefer to go along in my own kind of way."
