Rihanna has had a huge Egyptian tattoo underneath her breasts - and has shared the photo with fans online, naturally.

The huge inkwork, placed directly below the 'We Found Love' singers breasts, is a tribute to Dolly, Rihanna's grandmother who passed away following a battle with Cancer earlier this year. Posting the picture online, Rihanna wrote:  “Goddess Isis- Complete Woman – Model for future generations- #GRANGRANDOLLY – always in and on my heart #1lo,”

The tattoo shows Isis, an Egyptian goddess viewed as the perfect mother and wife as well as the patron of nature and magic. It was done in London prior to Rihanna's appearance with Coldplay at the Paralympic Games closing ceremony and is Rihanna's 18th tattoo.

Rihanna has had a busy time in London this weekend, adding a row with Piers Morgan on Twitter to the tattoo and Coldplay gig.

The pair fell out after Morgan, watching the ceremony from home, remarked on Rihanna's performance with Coldplay and her new short hairstyle by saying: "Love them or hate them, #Coldplay are a proper stadium band. Thus, ten times better than 95% of other musical acts at Olympics/Paralympics."

Adding: "ps I think @Rihanna needs to grow her hair back. Fast."

Rihanna did not take well to fashion advice from the TV star and immediately fired back at him, quoting the original Tweet and adding: "grow a dick..... FAST!!!!"

The pair did, however, make up and semed to agree a deal for Rihanna to be a guest on Morgan's US chat show.

Rihanna had a busy night last night, having joined Coldplay on stage inside the Olympic Stadium for a huge performance of their hit single 'Princess of China'.

In perhaps the worst kept secret in the music industry, Chris Martin brought out guests Rihanna and Jay-Z as part of the show - performing 'Princess of China' with Rihanna and a special version of 'Paradise' with Jay-Z.

Other hits that Coldplay performed included 'Yellow', 'Clocks', 'Viva La Vida' and 'The Scientist'. Watched on by all 4,200 of the Paralympic athletes competing i the Games, Rihanna also performed her hits 'We Found Love' and 'Run This Town'.
