Judith Katrijntje "Trijntje" Oosterhuis represented the Netherlands at the Eurovision Song Contest 2015 in Vienna, Austria. She is best known for being part of the group Total Touch from 1995 to 2001, with the songs "Touch Me There" and "Somebody Else's Lover" their best-known singles. She was also a coach on the third season of The Voice of Holland in 2012 - the last contestant from her team went on to win the competition. She returned to the coaching team for the fifth season of the series alongside her Eurovision predecessor, Ilse DeLange of The Common Linnets.
Trijntje performed the song Walk Along written by Anouk Teeuwe, who represented Netherlands in 2013 with the song Birds. She failed to qualify to the final. Her style choices, especially her first rehearsal dress and the outfit she wore for the semifinal, earned her the 2015 Barbara Dex Award. She announced the results of the Dutch jury vote during the 2016 final.
Her sister-in-law is Edsilia Rombley, who represented the Netherlands in 1998 and 2007.
