Even before his birthday, Ashton Irwin may have stepped into the deep end with Bryana Holly. According Unreality TV, Ashton Irwin revealed a deeper and more emotional side of him to talk about the upcoming new album.

He said, “We want to sort of have more messages for life involved in what we do, because we have a voice for young people.”

Ashton Irwin may be planning an exciting summer ahead with his girlfriend Bryana Holly. Seeing how 5 Seconds of Summer drummer just got into this hot relationship, he may be neglecting his work on new album.

In fact, he is so in love with his girlfriend Bryana Holly that he brought her on 5 Seconds of Summer tour 2015.

Ashton Irwin may make his relationship with his girlfriend even more official before the release of 5 Seconds of Summer new album. Seeing how 5SOS drummer has broken the band’s no-girlfriend rule for Bryana Holly, making their relationship public seems like the next logical step.

According to J-14, “ Ashton Irwin was caught hanging out with his rumored girlfriend Bryana Holly in Venice Beach! The 5 Seconds of Summer drummer was first linked to the model when they got cozy on a Disneyland date, and it seems like they're still hanging out.”

Do you think other 5 Seconds of Summer members are tolerating Bryana Holly? Do you think she will make an Instagram appearance before they release the new album? Let me now in the comments below!
