Rihanna is being sued for allegedly making defamatory comments about her former bodyguard.
The 26-year-old singer has been hit with a lawsuit from Geoffrey Keating, from Dublin, who claims the popstar made "nauseatingly offensive" and false statements about him in an email sent to him and his wife last July.
He also claims the star used the same defamatory allegations via a telephone call to his sister.
Mr Keating, who worked for Rihanna on her 'Diamonds' tour between October 2012 and July 2013, claims the comments have tarnished his reputation and damaged the future of his business.
The former bodyguard is seeking damages against the brunette beauty and he also wants her to publish a correction of the alleged defamation.
His lawyer, Gerald Kean, was granted permission yesterday (28.04.14) to serve the singer with the legal papers at her home in New York City.
Mr Kean told TMZ.com: "We're taking this battle very seriously. We are satisfied that the Irish Courts will see justice at the end of the day."

Hailee Steinfeld thinks Taylor Swift is an "amazing friend".
The 17-year-old actress has developed a close bond with the 24-year-old singer in recent years and the pair are often photographed out together, but the brunette beauty insists she prefers to keep their friendship out of the public eye.
Speaking in the May issue of Nylon magazine, she said: "She's an amazing friend. I always get the, 'Tell us something nobody knows [about Taylor] question.' And it's like, we both respect each other tremendously, but we choose to keep our friendship out of the public eye.
"She's a really great person and an inspiration to me and many others."
Despite being nominated for an Oscar award, the brunette beauty insists she's just a "regular teenager", but thinks her mother Cheri Steinfeld, who is also her manager, has helped her stay grounded after she was thrown into the adult world of Hollywood at such a young age.
She explained: "As strict as my mum is, I have so much freedom. Everything I do, she does with me and I couldn't imagine it any other way."

Beyoncé believes there's too much pressure on women to look perfect.
The 32-year-old singer has released a behind-the-scenes look into the making of her 'Pretty Hurts' music video, which is based on the standards of 'beauty' set by society.
The video director Melina Matsoukas said: "The concept of the video is really a behind the scenes look into society's take on beauty and how it doesn't bring you happiness and it doesn't move you forward in life. It's really finding yourself that brings you happiness."
The video demonstrates the extreme lengths women go to into order to fit in, and in one scene Beyoncé pretends she's preparing for cosmetic surgery and Botox.
She explained: "I'm pretending to get a face-lift and Botox. It represents all the things that women go through to keep up with the pressure that society puts on us. Some of the things that young women go through, it's just really heartbreaking for me."
The dramatic video was inspired by a photograph of Beyoncé as a child, standing in front of a fireplace, surrounded by trophies and awards she had won.
She said: "When you get this trophy and you're looking at it. Is it worth it?"
The video ends with the stunning singer smashing up her trophy display and admitting that beauty should come from within and the most important thing is happiness.
She concludes: "That song represents finding that one thing in the world that makes you really happy."

Cameron Diaz can't wait to babysit Drew Barrymore's daughters.
The 'Other Woman' star is planning to visit the 39-year-old actress and her children Olive, 19 months, and one-week-old Frankie, later this week, but she insists she'll soon be looking after the youngsters while Drew and her husband Will Kopelman enjoy a nice child-free night out.
Speaking to PEOPLE.com, Cameron said: "I haven't seen her [Frankie] yet but I'm going to this weekend. [Drew] is doing wonderful[ly]. Of course [I'll babysit], I'm an auntie!"
However, Drew recently admitted that she and Will prefer to care for their children without babysitters as they like to spend the weekends together as a family.
She said prior to Frankie's birth: "I am loving being a mum ... We spend every weekend together. We don't have a babysitter. It's just us. I can't wait to see how that's going to work out with the second one!"
Although, the blonde beauty may make an exception for her friend Cameron as they spent a lot of time together throughout her pregnancy at cookery lessons.
Drew said recently: "I really love cooking, it makes me so happy. But I'm terrible at it. None of it is effortless or sexy or even tastes that good for that matter, but I'm really working on it. I might travel somewhere to do it, and bring the family. I love cooking for Olive now, but I used to be Mrs Takeout.
"I've just never learned to cook in my life. Cameron's a great cook, and always has been. I'm just trying to catch up to that."

Robbie Williams is to become a father again.
The 40-year-old singer took to his Twitter account tonight (28.04.14) to announce that he and his wife Ayda Field are expecting their second child together and they're looking forward to their 19-month-old daughter Theodora 'Teddy' Rose having a sibling.
He tweeted: "Ayda and I are delighted to announce that Theodora Rose Williams is going to be a big sister. RW xxx (sic)".
The former Take That star, who married Ayda in 2010, was inundated with congratulatory messages from his fans after sharing the happy news.
Meanwhile, Robbie admitted in 2012 he was initially worried about becoming a father for the first time because he didn't know if he could "step up".
He said at the time: "I've been a very selfish person for a long time and I've indulged myself in every way possible.
"Then all of a sudden a person comes into the world that I've got to look after and be responsible for. I was terrified that I wasn't going to be able to step up and be the father I want to be to her."
However, he soon settled in to fatherhood and admitted last year he couldn't wait to expand his family.
He said: "My little girl is wonderful. Little Teddy. We are going to do more of them because they are amazing."

Evan Rachel Wood has a crush on Milla Jovovich.
The 26-year-old actress, who came out as bisexual in 2011, admits her husband Jamie Bell, 28, is well aware that she fancies the 38-year-old beauty.
During a Twitter interview on Sunday (27.04.14), Evan, who will sing with Milla for the LA Gay & Lesbian Centre on May 10, said: "My husband is well aware of the crush I have on Milla. I mean who doesn't?! (sic)."
Meanwhile, Evan - who has a nine-month-old son with Jamie - admitted she was scared about telling her parents about her sexuality, but was surprised by their reaction.
She said previously: "It's become more socially acceptable. With me, the reason why I came out is because I felt like now was the time to no longer be silent about it. I wanted to wait for the right time and wait to have enough years under my belt where people knew that it wasn't a phase or anything and I wasn't doing it for attention; this is a part of who I am, and I'm old enough to really know who I am by now.
"And I had to wait until I told my family, too, which I was really nervous about! And I have a really chill, understanding family, too."
Evan and Jamie first dated in 2005 but split up in 2008, before rekindling their romance in 2011.

Kendall and Kylie Jenner are reportedly glad they're no longer friends with Selena Gomez.
The 21-year-old singer reportedly cut ties with the sisters after the Coachella Valley Music and Arts festival earlier this month because she thinks they're a "toxic distraction" and she thinks they're encouraging her to be a party girl.
However, sources close to the reality TV stars claim Selena, who completed a three-week stint in rehab in January, is the one who is out of control, not them.
An insider told TMZ.com: "Selena has it twisted - not only do Kendall and Kylie eschew drugs and alcohol ... they believe Selena's the real drama-obsessed party girl. After all, she's the one who's been to rehab."
The source added that Kendall, 18, and Kylie, 16, "feel like they're better off without her".
The 'Come & Get It' hitmaker had formed a close bond with the famous sisters in recent months, but she made it clear their friendship was no more when she unfollowed them on her Instagram account last week.
Not only is Selena convinced the sisters are tarnishing her career, she also holds at grudge against them because Kylie was reportedly getting too close to her ex-boyfriend Justin Bieber, whom she has dated on/off for three years, at the music festival in California.
A source said previously: "Selena is convinced something has gone on between Justin and Kylie."

Josh Dallas reads to Ginnifer Goodwin's baby bump.
The 32-year-old actor and his wife are to welcome their first child into the world in coming weeks, and the hunky star admits he's been practising his story-telling techniques.
He said: "There was one stack of books, and I read all five of them and this one ['The Snatchabook', by Helen and Thomas Docherty] got a kick on the belly."
Although the couple are yet to announced the gender of the baby, Josh admits they've already picked out a name.
He told E! News: "We've got the name."
Meanwhile, the couple tied the knot in an intimate ceremony at sunset in Los Angeles in front of just 30 family members and friends earlier this month.
An insider said at the time: "Ginnifer and Josh seemed very relaxed and happy. They were surrounded by their nearest and dearest friends and kept it very intimate and simple."
Josh, who proposed to Ginnifer in October after more than a year of dating, admitted he was instantly attracted to the brunette beauty when he first laid eyes on her.
He said previously: "It hit me like a blinding light. I thought, 'I'm in trouble now.' "

Tori Spelling was hospitalised for an ulcer and migraines.
The 'True Tori' star spent at least six days at a medical facility in Los Angeles last week after reportedly failing to keep any food down and suffering from severe headaches.
A source told RadarOnline.com: "Tori's head hurt so much, she couldn't have any light in her bedroom and she couldn't keep any food down from the ulcer. She was in a great deal of pain and was very scared."
Friends believe Tori's health scare stems from extreme stress brought on by her husband Dean McDermott's confession to infidelity late-last year.
The source explained: "She was just so run-down and ragged from the affair fallout."
However, despite airing her marital breakdown on her lifetime reality show, the 40-year-old actress asked for the cameras to stop rolling during her hospital stint.
The source added: "For Tori, nothing is off-limits to the cameras. But production was not allowed to follow Tori into the hospital. She needed peace and quiet with no pressure."
Tori - who has children Liam, seven, Stella, five, Hattie, two, and Finn, 20 months, with Dean - was discharged from an undisclosed clinic on Saturday (26.04.14), but kept her pink hospital band on her wrist as she headed home.
It is believed Dean was by Tori's side throughout the duration of her stay in hospital.
A source said previously: "Dean would arrive by 10am and didn't leave until 8 most nights. He seemed very stressed out and worried."

Miley Cyrus is feeling "much better" following her severe allergic reaction.
The 'Adore You' hitmaker was hospitalised earlier this month after her body rejected Cephalexin, an antibiotic prescribed for the flu, but she insists she's on the road to recovery and she can't wait to resume her 'Bangerz' tour.
Speaking in a radio interview on 'On Air With Ryan Seacrest' today (28.04.14), she said: "I'm doing good. I'm much better ... happy to be getting back on the road. You have no idea."
The 21-year-old singer admits her five-day stay in hospital was so boring that she ended up splashing her cash on a hot pink mini-skirt that she'll probably never wear.
She explained: "I ended up doing way too much online shopping, and whatever they had me on to make me not in pain, I made some very questionable choices on what I bought. I don't know what this hot pink mini-skirt is that I bought in the hospital."
However, the blonde beauty insists one good thing did come out of her health scare and that was getting to ride in an ambulance for the first time.
She joked: "I went on my first ambulance ride. That, I was excited about."
Miley, who was forced to reschedule her US tour dates earlier this month, is looking forward to taking to the stage in Europe next month, but admits her allergic reaction can still flare up over the next 27 days.
She explained: "I should be all good ... it [the reaction] can happen for 5-27 days ... so it can come back within those 27 days but I've been very good."

Paul Simon and his wife Edie Brickell have been charged with disorderly conduct.
The couple, who have been married since 1992, were arrested on Saturday (26.04.14) after officers paid a visit to their home in New Canaan, Connecticut, to investigate a domestic "dispute", according to a police statement.
The police arrived at the scene at 20:00 local time after they received a phone call from someone at the home address, who then hung up without speaking.
Upon arrival, officers believed it was a case of domestic violence, but found very minor injuries.
Police chief Leon Krolikowski is quoted by Sky News as saying: "There was aggressiveness on both sides."
No further details about the dispute were released.
The pair, who have three children Adrian, Lulu and Gabriel together, were set to appear in Norwalk Superior Court, Connecticut, today (28.04.14).
Speaking outside the courthouse, the couple's lawyer Allan Cramer claimed the encounter that led to the arrests was "much less than nothing" and the pair have never had a disagreement like this before in the past.
Paul, 72, who has won 12 Grammy awards, first found fame as one half of the folk duo Simon and Garfunkel, while Edie, 48, was the lead singer of the band Edie Brickell & New Bohemians.

Diversity would like to be invited to Zayn Malik and Perrie Edwards' wedding.
The dance troupe - who shot to fame after winning 'Britain's Got Talent' in 2009 - would love to watch the couple, who got engaged last August, tie the knot in the near future.
Jordan Banjo, who has been linked to Perrie's Little Mix bandmate Jesy Nelson in the past, exclusively told BANG Showbiz: "It would be nice to go to their wedding."
Meanwhile, Perri Kiely is also hoping to receive an invite to the romantic nuptials as he's a "big fan" of the Little Mix girls and believes they're "incredibly talented".
However, the street dancers may need to wait a little while longer for their invitations as Perrie and Zayn are yet to set a time and place for their big day.
Although, Perrie, 20, has her heart set on having a Disney-themed wedding reception based on Mikey Mouse and his friends.
She said previously: "I do love Disney so [a themed wedding] would be amazing.
"I'm a big child. We are both big kids!"
Jordan and Perri are judging the Generation Green Energy Performance, a new initiative from British Gas that will see young people up and down the country compete to win an Energy Makeover worth up to £150,000 for their school.
