Marriage Boot Camp bust up: Heidi Montag and Natalie Nunn on a jealousy-fueled collision course following husband swap

Reality stars Heidi Montag and Natalie Nunn could soon be booting each other following a jealousy-filled husband swap on Marriage Boot Camp.

The exercise forced the girls exchange partners, with Spencer Pratt spending the day with Nunn, while her hubby Jacob Payne hung out with Montag.

And right from the start it seems like The Hills star is flirting with Nunn's man, almost like she wants to set her into a jealous rage.

While the pair go horse-riding with conveniently torn shirts, Montag wastes no time suggesting the football player take off the ripped t-shirt to reveal his even-more ripped torso underneath.

'If you want to take of your shirt for Natalie... that's what she would do!' she insists, pulling out her phone to take a photo. 

Heidi knows full well it was Nunn's raunchy 'butt selfies' on Instagram that landed her in Marriage Boot Camp in the first place, but wastes no time egging Payne on to try taking some provocative pics himself in his wife's absence... with Heidi as the willing photographer.

'Take it off Jacob!' she pushes. 'She loves Instagram, right?'

She continues to show contempt for her reality rival by probing: 'So what made you want to marry Natalie. Shouldn't she be nicer about what she does?'

Meanwhile Natalie opens up to Heidi's husband Spencer about just how jealous she is.

'I'm obsessed with Jacob,' she tells him. 'I warned him: "don't you look at anybody, don't take your shirt off, don't cook breakfast for anybody",'' she growls. 'There's a little jealously there.'

She is completely oblivious that at that very moment, Heidi is already trying her best to get Jacob to tick one of those things off that exact list. 

In a confessional, The Bad Girls Club star claims she's not worried about Heidi... but she is worried about what she might have to do to her.

'I'm not worried about him going with Heidi,'she insists. 'I'm just worried about me having to whoop her ass for doing some stupid sh*t. Because I'm not the one to be f**king with.'

Spencer meanwhile looks truly terrified for his wife.
