Celeste Barber took aim at Megan Fox and Machine Gun Kelly in her latest post on Instagram on Wednesday.

The 39-year-old comedian enlisted the help of her 'hot husband' Api Robin to poke fun at the attention-grabbing Hollywood couple.

Recreating Megan and Machine Gun Kelly's recent cover photo shoot for GQ Style, Celeste aimed a gun at her husband's crotch.

'He forgot to bring my pants so I shot him in the d**k,' she captioned the hilarious post.

The black and white photo sees Celeste sitting on a bench wearing nothing but skimpy lingerie and using her right arm to strategically cover her bare breast.

She glares at the camera as her husband stands alongside her wearing a trench coat, denim cut-offs and over-the-knee socks.

Actress Megan, 35, has been dating the 31-year-old rapper - real name Colson Baker - since May, with the couple regularly making headlines with their relationship.  

Celeste previously revealed that some celebrities have blocked her on social media during an interview with Jameela Jamil's iWeigh podcast in January. 

'If Cindy Crawford and Gwyneth Paltrow are okay with it, you can all f**king be okay with it!' she joked at the time. 

In an interview with The Guardian in June 2017, she admitted she gets annoyed with the fashion set thinking they're 'better than other people'.  

'I get a little miffed with fashionista people thinking that they are much better than other people because they are very slim and have architect husbands and get to wear free stuff,' she said. 

'It's a bit [like they are] rubbing your nose in, "This is how we live, sorry guys" - and that bums me hard.'
