"Fancy" hitmaker Iggy Azalea and her boyfriend Los Angeles shooting guard Nick Young attended three events together in two countries last weekend.

On June 21, Saturday, Iggy and Nick attended the 2014 Capital Summertime Ball in London. She wore a strapless, corset-style, skin-tight, blue denim knee-length dress with two tones matched with nude stilettos.

Later that day, she performed her chart-topping song "Fancy" at London's Capital FM radio event in Wembley Stadium before they went to Milan, Italy for Milan Fashion Week, Daily Mail reported.

While preparing to take off from Los Angeles to Europe, Iggy tweeted, "Me & my boo are on our way to you England."

The next day, the 24-year-old Australian rapper and the 29-year-old NBA player attended the Calvin Klein 2015 Men's Collection runway show in Milan, Italy, which featured Calvin Klein Creative Director Italo Zucchelli's menswear designs.

During the high fashion runway show, the couple wore subtly coordinated outfits and sat in the front row next to the New York Giants wide receiver Victor Cruz and Welsh actor and singer Luke Evans.

At one point, the couple was seen laughing with the "Fast & Furious 6" and "Dracula Untold" actor.

Iggy wore a tight pony tail and matched her eggshell-colored knit, figure-hugging mini dress with a cream jacket and cobalt blue pumps while Nick wore a black and blue plaid button-down shirt with jacket and black pants.

Iggy's pair of royal blue heels matched Nick's silky overcoat in the same shade. Looking simplistic and minimal, Iggy wore a gold necklace that read "Young Azalea" and no other jewellery.

It was at the 2014 Billboard Music Awards when Iggy and Nick first appeared together at a major celebrity event as a couple. They began dating in Nov. 2013, according to E! Online.

Weeks ago, Iggy celebrated her 24th birthday in Mexico with Nick, which also served as her celebratory vacation after having the number 1 and 2 spots on Billboard's Hot 100 simultaneously, a record which only the Beatles have achieved before, according to US Magazine.
