The pair got close as judges on season eight of the singing contest, with Guy Sebastian and Mel B joining them on the judging panel.
Adam’s contestant Isaiah Firebrace was crowned victorious on Monday (21Nov16), but Iggy bears no grudges against her fellow mentor after he surprised her with a necklace in the shape of an Egyptian ankh.
"Thanks @adamlambert for my gift!" she captioned a snap of the jewellery on Instagram. "It's been so much fun & so many laughs filming with you on the xfactor and I hope we still hangout in LA too! Love you #DivasForever."
Iggy was born and raised in Australia, but now resides Stateside. Talking about her feelings towards her home country in a new interview with GQ Australia, the Fancy hitmaker admitted she doesn't understand why people are so "offended" that she doesn’t miss living Down Under.
"Of course I like Australia, but I don’t know why people get so offended as it’s not my home. I don’t miss Australia, not because there aren’t great things about it," she sighed. "Emigrating when you’re a kid is a defining moment of your life, where you’re about to become an adult. That shapes you, I doubt you really understand the feeling."
Posing in a swimming pool wearing a wet white T-shirt for the Men of the Year issue, Iggy also touched upon the normality of her life.
"It’s weird to be normal now, right?" she mused. "There are varying degrees of normality depending on your level of insanity and environment. I’d be classified as normal for the environment I’m in but if you threw me into regular life, I may seem insane."
