With nine studio albums, two extended plays, six compilation albums, one soundtrack album and 54 singles, Christina Aguilera has a huge arsenal of hits to choose from.
The 41 year old singer opened her concert in Monaco with a slurry of blistering hits including Dirrty, Can't Hold Us Down, Bionic and the classic Genie In A Bottle.
After taking to the stage at 10.30pm at the stunning venue of Salle des Étoiles, Xtina received an enthusiastic reaction from the Monaco crowd.
The Monte Carlo Summer Festival audience sang along religiously to every song, with many even knowing the lyrics to some of the Spanish language tracks too.
Xtina, who is set to tour across the UK in August, showed that she still is the queen of vocal acrobatics as she flexed her four-octave vocal range.
Mixing together different genres and slipping effortlessly between ballads and upbeat dance numbers the Voice mentor kept the exclusive crowd hanging off her every decibel.
As her barnstorming performance came to a close she rounded out the concert with perhaps her most recognisable hit, Beautiful.
Xtina thanked the audience for their support and adoration before exiting the stage to more rapturous applause as red roses rained down from the crowd, having given them a five star performance.
Earlier this year she told Rolling Stone how much she valued her fanbase as she explained her connection with them.
Xtina said: "My fans are already so creative, and I know they appreciate authenticity, being a place that's important for me to come from.
"I love sharing and hopefully inspiring future generations through what I've built over decades and how they can build from that.
"Given that I also grew up in a generation where privacy is valued to the fullest, and not overly sharing on social media or putting out too much content, they know that when I do speak up or release something, it's something I value and believe in fully."
