Rihanna and Drake have become exclusive.
The 'Hold On, We're Going Home' rapper is reportedly the "happiest" he's ever been since rekindling his short-lived romance with the 'Pour It Up' singer and the couple are so smitten with each other they have decided to stop dating other people.
A source revealed to TMZ.com: "[Drake's] in the best mood he's been in a long time."
Insiders claim Rihanna, 26, is serious about committing to Drake, 27, because he treats her so well in comparison to her on-off ex-boyfriend Chris Brown, who left her bloodied and bruised when he physically assaulted her during an altercation in 2009.
The next step in the couple's relationship follows a series of outings together in recent weeks as Rihanna accompanied Drake in a number of locations including London , Paris and Amsterdam throughout the European leg of his 'Would You Like A Tour?' world tour.
Meanwhile, sources close to the couple claim Rihanna and Drake have been headed towards a relationship for a long while following their brief fling in 2009.
An insider told Hollywoodlife.com: "Rihanna and Drake really have this chemistry and vibe with one another and that's something they can't explain. They're both kind of infatuated with each other."

Cara Delevingne wants to marry Michelle Rodriguez and is planning their wedding.
The British model is reportedly "deadly serious" about making her relationship with the 'Machete Kills' actress official and she is hoping to tie the knot in a secret wedding at the Niagra Falls, Canada.
A source told the Daily Star newspaper: "It's typical of Cara to want to do something crazy and impulsive. But she seems deadly serious.
"They've talked about what kind of big day they'd have. Cara says she wants them to wed in their own element with no priest or anyone with a religious background."
It's thought Cara, 21, is keen to do something out of the ordinary and is eyeing up a helicopter ride for the nuptials.
The source added: "She thinks flying above Niagara falls would be perfect - like a no man's land."
The move towards an official declaration of love follows the couple's commitment ceremony during a trip to Thailand earlier this month, and although the proceedings weren't legally binding, they celebrated their blossoming relationship with a religious Baci ceremony known to locals as the kwan.
A source explained: "It can symbolise anything precious like a bond or an achievement, and shows how much they want to make a commitment to each other."

The couple reportedly celebrated their impending nuptials by throwing an intimate bash with their closest family and friends at The Carondelet House in Los Angeles last Friday (14.03.14).
According to US Weekly, Amber wore a white silk spaghetti strap dress which onlookers described as "vintage dressy", while Johnny sported a casual black suit and matching top hat.
Once inside the venue the happy couple indulged on a variety of foods, whilst guests danced to old rock songs such as 'Wild Thing' by The Troggs, 'Tutti Fruti' by Little Richard and 'Jailhouse Rock' by Elvis.
Johnny - who also has 14-year-old daughter Lily-Rose - was supported by his 11-year-old son Jack who attended with the actor's ex partner Vanessa Paradis.
Meanwhile, Aerosmith frontman Steven Tyler revealed the couple looked loved up during the party which was attended by the likes of Marilyn Manson, Mandy Moore and 'Pirates of the Caribbean' producer Jerry Bruckheimer.

David and Victoria Beckham's Hertfordshire mansion has been sold to a disgraced insurance tycoon.
The mystery buyer of the sprawling 12-acre estate - nicknamed 'Beckingham Palace' - has been revealed as Neil Utley, the chairman of Hastings Direct, who moved into the couple's former home last month after paying £11.5 million.
According to the Sunday People newspaper, the staggering sum also included the couple's Aston Martin and two Jaguars as part of the deal.
Last year Utley was ordered to pay £130,000 in tribunal costs and banned from working in the Lloyds market for two years after admitting 'detrimental' conduct during his time at motor insurance company, Equity Red Star.
Utley - who stepped down as chief executive of IAG UK, Equity's parent company in 2010 - had allegedly failed to take appropriate measures to ensure there were sufficient financial systems and controls over personal injury claims.
Victoria and David are believed to have used the money from the sale of their former Hertfordshire home to invest in their new £45 million mansion in central London, where they live with their four children, Brooklyn, 14, Romeo, 11, Cruz, eight, and two-year-old Harper.
The Beckhams reportedly earned £9 million in profit from the sale after buying 'Beckingham Palace' in 1999 just three months after their wedding.

Lady Gaga has defended her South By South West Festival performance against bulimia claims.
The 27-year-old singer sparked outrage when performance artist Millie Brown vomited on her during her rendition of 'Swine' at the festival in Texas on Thursday night (13.03.14), but she insists the "strange" act is helping to change the art world.
During an hour-long keynote speech at the event, Gaga explained: "Sometimes things that are really strange and feel really wrong can change the world.
"I'm not saying vomit is going to change the world. What I'm saying is it's the idea of a moment where it's truly just what we wanted to create and us just respecting each other as artists was enough for the performance to be worth it."
Demi Lovato - who struggled with bulimia - had accused Gaga of "glamorizing" the eating disorder after Millie drank bottles of coloured milk before sticking her fingers down her throat and regurgitating onto the 'Applause' singer.
However Gaga brushed off the accusations, insisting she's a long-time fan of Millie's work and loves collaborating with her.
Gaga added: "I've known Millie for I think like five years now and we've actually collaborated before, she was just in town and so we thought we would collaborate again."

Britney Spears has congratulated Jamie Lynn Spears on her wedding day.
The 'Toxic' singer described the nuptials as "magical" when she took to Twitter to express her excitement after her younger sister tied the knot with fiance, Jamie Watson, in New Orleans on Friday (14.03.14).
Britney tweeted: "Yesterday was magical. So happy I could be a part of my little sister's big day. Congrats @jamielynnspears!!(sic)".
The congratulatory message comes after reports there had been "lots of tears" from guests at the " very emotional" ceremony which took place at Audobon Tea Room Garden.
Jamie Lynn was accompanied down the aisle by her father, Jamie while her five-year-old daughter Maddie - whom she had with ex-boyfriend Casey Aldridge - led the proceedings as flower girl.
According to US Weekly, Britney's sons Sean, 8 and Jayden, 7, also played a role and were both dressed in black tuxedos and white bowties.
A source revealed to the magazine: "It was a beautiful ceremony and very emotional. Jamie Lynn was crying during the vows and Jamie looked like the happiest guy I've ever seen get married."
The duo sparked speculation they were getting hitched after it emerged they obtained a marriage licence from Tangipahoa Parish Clerk of Courts earlier this month.

The 37-year-old actress - who plays Michelle Connor in the soap - has been offered a new deal, which is said to include promises of dramatic storylines over the coming months.
An insider told The Sun on Sunday newspaper: "Kym is at the very centre of the show and there was no question that we would want to sign her up for another year.
"The scriptwriters are planning fantastic storylines for her later this year."
Kym's decision to stay gives the soap a boost as they prepare for the impending departures of Michelle Keegan, Sue Johnston, Chris Gascoyne, Charlie Condou and Phillip Lowrie.
Meanwhile, Bill Roache - who was recently cleared of historic sex assault and rape charges - has had an emotional return to the cobbled set of the show.

Ronnie Corbett retires from showbiz as he battles a "mystery" illness.
The 83-year-old legendary comedian has brought an end to his famed TV career as his wife Anne insists he isn't going to keep going like 'Dancing On Ice' host Bruce Forsyth.
She told the Sunday Mirror newspaper: "He won't be doing any more TV - he's 83. He won't be like Bruce Forsyth."
It is said he is likely to need more tests to find out exactly what he is struggling with, as he battles health issues including chest pains.

"He was feeling sick in his stomach and he wasn't well. The hospital ran lots of tests, he was in there for several days."

Tinie Tempah always sips on mint tea backstage before his concerts.
The 'Pass Out' rapper admits his tour rider isn't very rock 'n' roll and although he has a small amount of alcohol in his dressing room, his favourite thing to indulge in before a gig is home-brewed, fresh mint tea.
Quizzed about his concert must-haves, he said: "When I first started out, it was an abundance of sweets, but now it's very practical things. I like a good mint so, I've got fresh mint leaves to make my own tea, which is cool I have popcorn, I love sweet and salted.
"I have scented candles because it gets a bit sweaty in there with all the lads coming off the stage. A nice bottle of champagne to pop if the show goes great, too, and we have a shot of Jack Daniel's or some vodka before the show."
The stylish star was recently spotted with One Direction singer Harry Styles at London Fashion Week and says he always has time to catch up with the group.
Tinie told heat magazine: "It's always good to see Harry. From 'The X Factor' to where 1D have come now, it's a blessing. I'm always very happy for them. I brought them out on my show once and I have a lot of time for Harry and vice versa. We were just ogling models, as you would."

Brad Pitt wants his children to be "proud" of his work.
The 50-year-old actor - who raises Maddox, 12, Pax, 10, Zahara, nine, Shiloh, seven, and twins Knox and Vivienne, five, with fiancee Angelina Jolie - admits these days, his career choices are based on whether he will be happy to show the movie to his six kids when they get older.
He said: "The key for me [when choosing a film] is to leave something behind that will make my kids proud.
"I want to be able to show my films to my children and say, 'Your daddy made this.' "
The 'Moneyball' actor admits he struggled early in his career because he felt "lost" and took too much advice from other people, but he is now much more confident in the choices he makes.
He told Britain's OK! magazine: "When I was starting out, I didn't really follow my instincts. I felt kind of lost.
"You get a lot of advice from people who are trying to advance your career and make money off you - and that isn't necessarily a bad thing, but it isn't always going to lead you to make good films.
"But eventually, I figured out I was in the game to tell personal stories. I wanted to be able to add something to a film that was different to what anyone else could bring."

Rihanna is completely obsessed with Wotsits.
The 26-year-old singer is said to adore the cheesy-flavoured snack, which she ordered when she was staying at London's luxury Cafe Royal hotel - with boxes being paced in the limo she was travelling in so she could still enjoy them whilst on the move.
A source told the Sunday People newspaper: "Rihanna's love for Wotsits has caused much laughter among the staff. They find it very funny that the star would be so hooked on them.
"We're not just talking the odd packet here and there. She wants boxes of them on hand for whenever she fancies them. It is utterly bizarre but she just can't get enough of them.
"She is constantly asking for them to be delivered to her hotel suite ad her car also has to be fully stocked with them."
This comes after a film was revealed of the 'Pour It Up' singer pushing a man out of the men's toilet so that she could use it.
She was spotted entering the restroom and grabbing an unknown male by the arm before shoving him out and closing the door behind her, during her recent trip to Zouk Restaurant, Manchester.

Simon Cowell has bought his baby an Aston Martin pram.
The media mogul - who, along with his partner Lauren Silverman, welcomed their son into the world last month - has paid £2,000 on the top-of-the range buggy so that Eric can enjoy the same luxuries in life as his father.
A source told The Sun on Sunday newspaper: "Simon is used to enjoying ultimate luxury wherever he goes and of course he wants the same for his son."
The couple bought the pram during a recent shopping trip to Harrods, leading the upmarket department store to sell out of the item - with only 800 models made - which they describe as "the world's most outstanding contemporary baby travel system".
The store also claims it "cocoons and protects like no other".
The pricey pram features a hand stitched Italian leather interior, and is modelling off the £1.2 million Aston Martin One-77 coupe.
Simon recently insisted he was "born" for fatherhood, although he admitted he had his doubts before the birth of his son.
He said: "I was born to be a dad ... I actually said to Lauren beforehand, 'What if I like the dogs more than him?' - and she said, 'You're gonna be absolutely fine,' and then literally within seconds of him being born, I got it!"
