5 Seconds of Summer singer Luke Hemmings’ former girlfriend Aleisha McDonald made clear that she does not like Luke once and for all on Twitter. Unfortunately, her attempts backfired and she got a lot of hate. Meanwhile, 5SOS Luke Hemmings have been showing signs of burnout, posting tweets that hints at his tiredness and closing his Instagram account. Is 5 Seconds of Summer band leader ready to call it all quits?

Aleisha McDonald decided to wish her ex-boyfriend Luke Hemmings happy birthday last week. That tweet was one of her most favorited and retweeted messages ever.

Happy Birthday @Luke5SOS

When other Luke Hemmings girlfriend wannabes freaked out, Aleisha McDonald posted another tweet saying, “People, I don't like Luke, just wanted to say happy birthday”. Of course, the really crazy 5 Seconds of Summer groupies started calling her a fake saying things like, “you seriously need to just delete this account and stop pretending to be aleisha why do you even do it?” and “THIS IS FREAKING FAKE GUYS STOP BELIEVING STUFFS SHE SAYS, THE REAL ALEISHA DEACTIVATED HER ACCOUNT. UGH”. 5 Seconds of Summer Luke Hemmings’ former girlfriend defended herself with another tweet.

Life is hard for the ex-girlfriend of 5 Seconds of Summer singer.

But life is even harder for Luke Hemmings himself. He has been showing signs of fatigue and burnout as he trudges through the second week of U.S. tour and promotions. His tweets have been filled with specks of negative energy lately.

It's my day off, I can wear jeans and flip flops if I want — Luke Hemmings (@Luke5SOS) July 27, 2014

Luke even closed his Instagram account, which he used to update with behind-the-scenes pictures of the 5SOS boys.

With all the media appearances, publicity stunts and fan signings, it’s understandable that the entire 5 Seconds of Summer boys are feeling a little under the weather. Even their smiles on Twitter photos starting to wane as the weeks go by.

But there still is hope that the boys are maintaining the romantic side of them. Luke Hemmings is still posting vague romantic tweets that still has the 5 Seconds of Summer fans on the edges of their seats.

I'm latching onto you
