Iggy Azalea and Nick Young celebrated their one-year anniversary Sunday by shopping at Target.

The 23-year-old rapper and her NBA star boyfriend marked the romantic occasion by stopping by the discount store after they spent their first date shopping for socks at the popular store last year.

Taking to his Instagram account, Young posted a picture of Azalea, which he accompanied with the caption: "Happy Anniversary boo thang ..1 yr ago I put my Mack down and took this girl on a date to Target, and she's been trapped since. LOL."

The 'Fancy' hitmaker also took to Instagram to post a picture of herself and her beau outside the store, which she accompanied with the caption: "It's our anniversary #SeriousTho #LoveYouBoo."

However, Young didn't just treat Azalea to a shopping trip; he also splashed out on two bouquets of red roses.

Meanwhile, Azalea insisted earlier this year that there was some bizarre logic behind her choice of date last year as she believes you can really get to know someone based on their shopping taste.

She said: "You can really get to know someone at Target so I was like, 'What quilts are you into? What's your favourite movie? What snacks do you like?' "
