Shawn Mendes is expected to appear at next month's 2018 iHeartRadio Music Awards and when he does, he could be walking the red carpet with his rumored girlfriend, Hailey Baldwin, on his arm.

Because Mendes is up for several awards during the show, including awards for Best Lyrics and Best Music Video for "There's Nothing Holdin' Me Back," it's safe to say that he will likely be in attendance at the event. Meanwhile, Mendes's rumored girlfriend, Baldwin, is hosting the event alongside DJ Khaled.

In addition to the two nominations mentioned, Mendes is also up for Best Fan Army, Male Artist of the Year, and Best Cover Song for "All We Got."

Mendes and Baldwin have been rumored to be dating for the past several months but recently, the singer turned up with Camila Cabello and many believed he could be two-timing the model. As some might have noticed, the two singers looked to be quite cozy with one another while out in New York City last month. That said, Cabello has denied their romance on multiple occasions.

Sure to make things awkward between the trio is the fact that Cabello will also be present during the awards show in March at The Forum in Los Angeles.

As Baldwin gets excited for her upcoming role as the show's host, Cabello is getting pumped about her upcoming performance.

As for the rest of the show's lineup, a number of other musicians are scheduled to perform, including Ed Sheeran, Cardi B, Maroon 5, Charlie Puth, and the Backstreet Boys.

When it comes to Baldwin and Mendes' relationship, they appear to be quite serious about one another, despite having remained silent about the nature of their relationship for the past several months. In fact, in December, Baldwin was spotted with her arms wrapped around Mendes as they went for a stroll in his hometown in Canada.

Around the same time, a source told E! News that Baldwin and Mendes started off as friends before allegedly embarking on a romantic relationship.

“It started out casual, as they would run into each other at parties and hang out, but most recently it’s become more serious,” the insider shared. “They are definitely dating and spend a lot of time together…a few months ago they were sneaking out of public venues like Delilah while trying to not make a scene and now they have gone on private vacations to Europe."
