Taylor Swift marked a major career victory on Saturday night (July 11), when she received No. 1 plaques for four of her recent singles.

Big Machine Records President/CEO Scott Borchetta was on hand backstage before Swift's gig at MetLife Stadium in East Rutherford, N.J. to present the country-turned-pop superstar with plaques commemorating the chart-topping success of “Shake It Off,” “Blank Space,” “Style” and “Bad Blood,” all of which reached No. 1 on Billboard's Radio Airplay chart.

All four singles hail from Swift's first-ever pop album, 1989, which has sold more than five million copies since its release last October. According to a press release, that makes it the fastest album to move five million units in the last decade. In fact, 1989 surpassed the Frozen soundtrack to become the best-selling album of 2014 despite having been released in the final sales quarter of the year.

Swift's 1989 world tour kicked off in Japan in May, and it is scheduled to run through December before wrapping up in Australia. The tour has been commercially and critically successful, playing the biggest venues in the world and earning glowing reviews across a wide spectrum of media, including Rolling Stone, which opined, “Never one to do things halfway, Swift has made this a pop show — or rather the pop show, as far as 2015 is concerned.” The New York Post weighed in with, "Swift has become a commanding stadium-sized pop star," while Billboard says, “[The 1989 World Tour]'s the obvious end result of Operation 1989 World Domination.”

Saturday's gig was Swift's second straight night at MetLife Stadium, where she drew 120,000 fans in total. The previous night she was joined onstage by a number of special guests, including the U.S. women's soccer team, Lena Dunham, Hailee Steinfeld, Gigi Hadid and Lily Aldridge, Heidi Klum and the Weeknd.
