Proving there's only one man who can get their hands on her derrière, Millie has now had her pants personalised with her husband's name on them.
Yep, we're not kidding!
Showing off her pink pair to fans, Millie took a snap of her new undies that prove she is officially off the market.
How you ask? Why they say 'Stephen's Mrs' of course!
Stephen is the first name of Millie's husband Professor Green and alongside her photo, the now turned fashion designer joked: "Hands off this tush is taken! Thanks @lilfortescue @cheekfrills1."
Chelsea girl Millie tied the knot with Professor Green back in September 2013 in a romantic ceremony at Babington House, Somerset.
Only recently, Millie was seen reminiscing about her big day and the starlet has made no secret of the fact she is keen to start a family with Pro Green.
Earlier this year, rumours surfaced that the former reality star was expecting, but Professor Green was quick to shoot such claims down.
In February he tweeted: "The Internet is a funny place… The Mrs is has been called pro-anorexia and pregnant in one day." Posting five emoticons of poop, he added: "What a pile of..."
Millie, however, has said she is hoping to have her first baby with Pro Green in the next five years.
Admitting she'd like to be a young mum, the 25-year-old said: "I'd like to have kids by the time I'm 30."
Could it be a case of watch this space, then?!
