The 28-year-old saw British chart-toppers Mumford & Son, who performed to a sell-out crowd over the weekend.
The glamorous wife of Irish soccer captain Robbie Keane described the gig as "amazing" before adding: "Really lifted my spirits after a hard week ... great band."
Mum-of-one Claudine had enjoyed the night out with her younger brother Ronan and her Ireland soccer star hubbie Robbie following a tough few days which saw her family bury 88-year-old Margaret 'Lil' Conway.
Among those who messaged Claudine back was pal Yvonne Keating, who told her the gig was "just what you needed".
Malahide native Claudine was knocked for six after her grandmother Margaret -- to whom she was very close -- passed away last Tuesday.
She had flown home with her footballer husband Robbie (32) and their young son Robert Jnr (4) after hearing the bad news that her granny was unwell.
The mother of her mum, Joan Palmer, passed away two days after the pair landed back from LA and she was laid to rest in her home town of Stradbally, Co Laois at the weekend.
She was buried after a Mass at the Sacred Heart church and Claudine spoke fondly of her in her homily, describing her as a "fantastic mother, sister, grandmother and great-grandmother."
Claudine told the congregation how many of their fondest memories as children were going to the bingo on Friday night with granny.
"We will have an emptiness in our hearts without nanny. Thank for you looking after us," she said. Claudine had also paid tribute to the staff at Beaumont Hospital for looking after her so well during her final days.
She and Robbie will celebrate Christmas at home in Dublin as she catches up with her family and friends.
The couple have been living in LA after Robbie signed up with LA Galaxy in August 2011.
And they have really settled into life in the sun-kissed city, regularly rubbing shoulders with his former team-mate David Beckham and wife Victoria.
