Caitlin (alias Kathleen Goossens) was born on May 23, 1976 in Heist op den Berg, Belgium. The musical history of the family goes back to the grandparents. Her grandfather was an accordion player for The Rainbows, he was also the producer and the manager behind several Belgian artists. Besides this, the grandparents were running a publishing and a record company.

Caitlin's mother owned (and still owns) a record store and it is in that shop that Caitlin spent her childhood and her interest in music was born. After finishing her marketing studies she took a part-time job in the artist agency that her sister ran and as a result, ended up singing for the popular Belgian dance formation Astroline...one of her sister's company's clients.

Astroline had several top ten hits like Feel The Fire and Smiling Faces and things were busy, until they decided to split. Caitlin took a break from stage, but as a singer she still did several studio jobs, until she was contacted by the producers of Orion Too. Since then Caitlin has sang almost exclusively for Orion Too and there doesn't appear to be any signs of either Orion Too or Caitlin slowing down any time soon.
