There's nothing wrong with bearing some skin on hot days, and Gigi Hadid is a testament to that!

The 20-year-old model definitely grabbed the attention of on-lookers on Friday, when she arrived at BFF Taylor Swift's LA concert with boyfriend Joe Jonas.

Opting for something more comfortable probably, Gigi Hadid was sporting a black bodysuit that showed off her cleavage and some sexy side boob! She paired the look with a black and white net-printed skirt, along with some Adidas Yeezy Boost 350s!

Not only that, but Gigi Hadid's boyfriend Joe Jonas were also wearing the same sneaks! The 26-year-old Jonas brother paired the sneakers' white version with black jeans, a black bomber jacket, and a black printed shirt.

Taylor Swift used to date Joe Jonas a few years ago - and there seems to be no "Bad Blood" between them!

In fact, Gigi Hadid and Joe Jonas went on a double date with Taylor Swift and Calvin Harris back in June; where Karlie Kloss joined the fun as a fifth wheel.

Taylor Swift is currently on her 1989 world tour, who made a stop at the Los Angeles Staples Center on Friday. Taylor Swift even had large number of celebrity attendees at the event!

Taylor Swift has been bringing out guests to appear on various shows on her world tour. For the LA show, Taylor Swift recruited NBA legend and LA Lakers star Kobe Bryant.

Not only that, but T-Swizzle also performed alongside OneRepublic's Ryan Tedder. The two performed the band's 2013 hit track, "Counting Stars."

Although she wasn't on stage this time, Mariska Hargitay was spotted in the audience. Helen Hunt, Jesse Tyler Ferguson, Mark Wahlberg, and "Real Housewives of Orange County" star Lizzie Rovzek were there too - they even got the photos to prove it (check them out below)!
