Model Hailey Bieber has slammed trolls who suggested that she is "second best" to husband Justin Bieber's ex-girlfriend Selena Gomez.

The 22-year-old had posted up a picture of her and 25-year-old Bieber earlier in the week and many followers immediately began commenting that the "What do you Mean?" singer actually preferred 26-year-old Gomez.

According to Fashion Magazine, Bieber and Gomez had been in an on-and-off relationship from 2011 until March 2018. In an Instagram story put up on April 25 that was since deleted, Hailey wrote: "You little internet kiddos need to learn how to move on for real."

She continued: "We’re adults that have better things to do than waste time explaining something just so you can stop your delusional fantasies." The post, which was captured via a screenshot by fans, ended with Hailey saying: "I’m not gonna sit here and let obsessive strangers try to tell me about my own husband, you wanna talk about somebodies [sic] husband then get ur own. G’night!!"

The comments that Hailey was slamming have been deleted since the incident but several screenshots made their way onto social media, Fox News reported. One user reportedly wrote: "Can you stop forcing your relationship already… we all know your 2nd best. You always will be and always have been… [sic]"

Another person is reported to have commented: "He will leave you one day and he will go to Selenaaaaaaaaaa." And a third wrote: "You’ll never be @selenagomez never ever."

Bieber and Hailey tied the knot at a courthouse in New York City in September last year after they were reported to have been dating for just 12 weeks. The "Sorry" singer did his fair share of slamming trolls in March this year after some of them suggested that he didn't love Hailey.

One spiteful commenter wrote on a photo that Bieber had posted on Instagram: "You are NOT in love with Hailey! You only married her to get back at SG plus Hailey sleeps with men like @shawnmendes for fame and she’s racist." 

The star decided to jump into the comments section of his own post to hit back saying: "Ur immature. the fact that you have an account dedicated to dissing my wife and I is absolutely absurd. why would I dedicate my whole life to someone in marriage to get back [at] my ex. Anyone who believes this is mean spirited or 10 years old or younger because a logical person doesn't talk or think this way. u should be ashamed of yourself really. [sic]"
