There's nothing more awkward than sending a text to the wrong person, especially if that message is intended for you ex and you've sent it to your current beau.

Right, Prince Harry?

Reports from Now Magazine claim that the third in line to the British throne accidentally sent a text to current flame Cressida Bonas, reminiscing about his previous relationship with ex Chelsy Davy.

The two, who dated on and off for seven years, apparently got in touch again just recently, after Chelsy wished him the best in his new relationship and said she thinks Cressida is a nice girl. Since then, the ex lovers began exhanging friendly text messages reminiscing about the past.

One of their text included Harry saying he had listened to Rihanna's Only Girl (In the World) and telling her that the song reminds him of her.

"That was our song... It still reminds me of you," read the alleged text message.

Cressida, on the other hand, was reportedly (and understandably) less than impressed after the incident.

According to Now, the red-headed royal even tried to cover up for his mistake, but what happened was pretty obvious.

"He was totally mortified about it all - it was such a simple mistake and 
it ended up causing him a lot of hassle and heartache," a source revealed to Now.

Prince Harry and Cressida have been dating for months now, after making their first public appearance together on the slopes of Swiss ski resort Verbier. Since then, their romance seems to be heading into a serious direction, with the couple being seen enjoying a fun-filled night in London last month and Harry claiming she is 'the one.'

But now, we just wonder how this will affect the relationship of the loved-up couple. Let's hope it's nothing serious though!
