Justin Bieber and Miranda Kerr Dating? Selena Gomez's ex 'flirty' texts REVEALED, 'dirty talk' with sexy Victoria's Secret model leads to Orlando Bloom divorce?

Earlier this month, reports confirmed that Victoria's Secret beauty Miranda Kerr and "Pirates of the Caribbean" heartthrob Orlando Bloom were separated. A rep for the ex-couple released this official statement:

"Orlando Bloom and Miranda Kerr have announced that they have been amicably separated for the past few months. After six years together, they have recently decided to formalize their separation."

Rumors even suggested that Bloom was cheating on his wife with "Romeo & Juliet" co-star Condola Rashad - check it out:

But NOW rumors have it that 30-year-old Kerr was actually the one perhaps cheating... with 19-year-old "Believe" crooner Justin Bieber!

An alleged source for Us magazine claims that the gorgeous model was "always very flirty" with Selena Gomez's ex. The duo hung-out backstage after last winter's Victoria's Secret Fashion Show. Apparently, they even started "sexting" and sending flirty messages to each other!

Another insider tells The Mirror, "Orlando heard that there had been some ­flirting ­going on and he wasn't exactly thrilled about it."

So that put some tension on their marriage and the couple started fighting a lot - and now they're headed for divorce.

Interesting...

FYI - when Bieber and Kerr started "flirting," the Biebs was still dating Gomez...

Now if only those "kinky" texts would leak online if the rumors are indeed true!

Do Mstars fans think Bieber and Kerr have something romantic going on?
