Claudine Keane was with singer LeAnn Rimes the night before she cancelled her Dublin gig.
Claudine (29), who is married to Irish skipper Robbie Keane, tweeted on Thursday morning that she enjoyed her "sing-song" with country singer LeAnn and her husband Eddie Cibrian.
"Had the most amazing singsong with @leannrimes & @EddieCibrian. She's the most incredible singer. What a fun night, thanks guys!! Cxx," she wrote.
There is no mention of where the sing song took place - and no mention of Dublin nightclub Copperface Jacks late on Wednesday night.
Singer LeAnn was later pictured in Copperface Jacks - although there is no suggestion that Claudine was in her company at that stage.
The 'Can't Fight The Moonlight' singer was scheduled to play before 1,000 Irish fans at Vicar Street on the following night.
But on Thursday afternoon, the singer took to Twitter to complain she had been in such pain with a sore throat that she was forced to go to a Dublin hospital.
She tweeted: "Never thought I'd see the ER in Dublin. I have coughed myself into pain. The spasm is intense. Being human sucks sometimes."
Following LeAnn's trip to a hospital, Aiken Promotions apologised to up to 1,000 fans – many whom travelled across the country – for the cancellation of the gig.
"LeAnn Rimes regrets to announce that due to illness tonight's performance at Vicar Street has been cancelled. She would like to apologise for any inconvenience caused," the promoters said.
Manager at Copper Face Jacks, Aidan McCormack tweeted a photo of the singer in the club on Wednesday night.
"LeAnn Rimes popped into Coppers tonite couldn't get her up on the bar counter!" – a reference to her dancing on a bar counter in the 2000 film, Coyote Ugly.
When contacted by the Herald, Mr McCormack said: "I can't comment on anything, I am off today. I haven't been working the last few days."
The picture of Rimes in the club has been deleted from his account.
On Friday, the singer seemed to have recovered somewhat and was photographed out and about in the city centre with with husband Eddie Cibrian.
She tweeted: "Got a massive shot in my ass OMG it freaking hurts I'm limping down the streets of Dublin. This could sound really bad on so many levels."
Contacted by the Herald and asked to comment on her visit to Coppers on Wednesday night, a spokesperson for Rimes said she was recovering.
"LeAnn is currently on vocal rest in her hotel room under a doctor's care and vocal specialist due to a resurgence of a viral infection that she has been struggling with the past two weeks," the spokesperson said.
Management also released a statement from the throat specialist who treated her in Dublin.
"Since recovering from a recent viral infection LeAnn has a lingering chest cough.
"The continuing spasms has caused swelling in the soft tissue of the throat and swelling of the vocal chords.
"She's been prescribed steroids and voice rest until her next show and will be taking it day by day to make sure there's no further injury to her instrument," the specialist said.
American country-pop singer Rimes is scheduled to perform at Birmingham's Symphony Hall this evening.
The star will then fly to Glasgow for a set at the Glasgow Royal Concert hall.
Rimes first sprang onto the music scene when she was just 13 years old and her breakthrough single Blue made it into the Billboard top ten charts.
She was the youngest recipient of a Grammy Award, and has been likened to Patsy Cline.
She's best known for her hit singles How Do I Live?, Life Goes On and Can't Fight the Moonlight.
