The 'Bad Boys' singer got the words "Honour, Love, Trust" tattooed on three of her fingers, and "Love & Loyalty" scrawled on her chest near her collarbone.
Alexandra showed off the process to her fans through a series of photos on Instagram after getting the inscriptions at renowned celebrity tattoo parlour, Bang Bang.
Despite going through the painful process, the 24-year-old seemed to handle it well and was all smiles as she posed for a photo with the tattooist.
Alex, who wore a black crop top, captioned one snap: "Smiling through this damn pain lmfao."
Alex is no stranger to tattoos after getting an Egyptian Royal Nefertiti figure inked onto her right side in April. She also has five stars etched along her left earlobe and a heart drawn behind it.
It's no surprise that Alex chose Bang Bang, as the parlour has given tattoos to the likes of Chris Brown, Rita Ora and Cara Delevingne. More recently, 'Skyfall' singer Adele popped in last week to get the word 'Paradise' inked on her left hand.
Former X Factor winner Alex, who recently parted ways with her record label RCA, has been in New York since June working on new music for her third studio album.
Last month, she wowed crowds in New York after performing with musical icons at a Chaka Khan tribute show.
