Rihanna reportedly almost scrapped a gig in Dublin on Friday after suffering a meltdown hours before she was due on stage.
According to The Sun, RiRi almost cancelled the Irish concert after feeling the pressure of her world tour and only decided to perform after making a tearful phonecall to mentor Beyoncé - who was able to persuade her to carry on with the show.
The We Found Love singer eventually went ahead with the gig, writing online after the concert: "I'm so light-headed!"
It is thought the 23-year old is suffering from exhaustion as a result of her huge ten month 101-date tour, with a source telling the newspaper: "She's just a young woman who just wants to have fun, but she was feeling pretty low."
"It's a mix of exhaustion and stress. She's been partying hard to take her mind off things, but there are days when she wakes up and doesn't even know where she is because of the travelling. It's no wonder she is feeling down."
Pregnant Beyoncé is thought to have advised RiRi to complete her tour commitments, then take a year off - much like she did in 2009 when Queen B took a break to spend some time with hubby, Jay-Z.
The insider added: "She knows Rihanna needs downtime or she'll burn out."
Despite feeling under the weather, it seems the Bajan babe's hard work is paying off after she topped both the official UK singles and album charts over the weekend.
She has become the first female artist ever to top both charts at the same time twice in one year with different releases, as We Found Love stopped Olly Murs reaching the summit in the singles chart, while her new album, Talk That Talk took the album countdown No.1 spot.
