Two of Mick Jagger's young lovers locked in bizarre Instagram showdown after emotional posts

Over the last decade or so, social media has become just about as ubiquitous in our lives as running water and that one Justin Bieber song which won't stop playing on the radio.

This isn't necessarily a bad thing, of course, as the likes of Facebook and Instagram have allowed us to stay in touch with friends all over the world, connect with new people in a relatively easy way, and keep up with what everyone is doing when you don't have the time to meet face to face. But it definitely has its downsides - the main one being that it's difficult to have a private life when your every waking moment is documented on Snapchat.

This becomes especially problematic when you have more than one private life, as two of Mick Jagger's girlfriends are now aware of.

The 74-year-old Rolling Stones star has always been known as somewhat of a ladies' man, and, even though he's only been married once, he's had eight children with five different women. The youngest of his children is 16-month-old Deveraux Octavian Basil Jagger, who is technically an uncle to Jagger's older grandchildren.

Deveraux's mother is 31-year-old Melanie Hamrick, who, for all intents and purposes, believed her relationship with Jagger to be monogamous. However, on Monday of this week, she may have been proven wrong.

Noor Alfallah, a 22-year-old film producer from California, took to Instagram at the beginning of the week to share a picture of herself and the rockstar - and the pair appear to be pretty intimate with one another.

With his arms wrapped tightly around Alfallah from behind, Jagger looks happy as he smiles for the camera alongside his former bandmate, Ronnie Wood, and his wife, Sally Humphreys. The 22-year-old captioned the photo, "Same time last year! Miss you guys!"

Jagger's fling with Alfallah was known about in October last year, as he and Hamrick were on a break at that point. However, as Alfallah's caption shows, their relationship was happening long before that point - and perhaps might still be going on behind closed doors today.

Since the time that photo was taken, however, Hamrick and Jagger rekindled their romance... so it was sort of awkward when Alfallah posted such a blatant throwback to her time with the musician. By way of response, then, Hamrick posted her own dedication to her partner just a matter of hours later.

Since then, Hamrick has not posted anything else, and Alfallah has actually made her account private so that nobody else can see her pictures - leaving both of them in a weird stalemate situation.

Jagger, meanwhile, has made no comment on the bizarre uploads, and instead has posted his own (totally unrelated) content on his Instagram page. Perhaps he's trying to show he isn't letting the posts bother him, or maybe it's a cover for the sheer turmoil that's going on in his personal life at the moment.

For now, though, we can only speculate.
