Kanye West is designing his 15-month-old daughter a diamond wedding ring.
The 36-year-old rapper is keen to create North West's first ever band, which will have the little one's name engraved on it and feature a diamond big enough to ensure she can wear it now.
A source said: "He's in the process of designing her a one-of-a-kind diamond ring for her to wear on her wedding finger. It symbolises dada's love for his little angel.
"Call him crazy, but that's what he's doing. He says it's going to be princess cut with her name engraved in the band and will have the biggest diamond on it that she can possibly carry on her little finger."
The rapper has enlisted the help of jeweller Lorraine Schwartz - who created his wife and North's mother Kim Kardashian West's engagement ring - to create the special band, and he "doesn't care" if the gift seems a little extravagant.
The source added to HollywoodLife.com: "He will be the first man to put a ring on his girl's finger. He's waiting until she gets a little older and will have Lorraine make it to fit her little finger.
"He will do nothing short of spoiling her because that's what he wants to do.
"That little girl means everything to him and there's not a limit on what she can have. He's lucky to be doing it and incredibly thankful, too."
News of Kanye's gift comes shortly after it was revealed Kim has hired a tailor and stylist for North to ensure her little one has outfits which coordinate with her own.
A source said: "Kim has hired North her own personal tailor whose sole job it is to make mini versions of Kim's designer outfits and ensure they always co-ordinate.
"The tailor, who is also paid to act as North's stylist, works with Kanye and Kim's styling team to create her looks.
"Some are collaborations or commissions to designers themselves and others are created in-house."

Brooklyn Beckham had to ask his mum's permission to stay at a film premiere on Tuesday evening (07.10.14).
The 15-year-old son of power couple David and Victoria Beckham was seen sneaking a quick phone call in to his fashion designer mother to check if he was allowed to stay out late, despite it being a school night.
The teen heartthrob - who is rumoured to be dating 'Kick-Ass' actress Chloe Grace Moretz - was chatting with celebrities including Elizabeth Hurley and former England footballer Sol Campbell at the swanky premiere in Kensington, west London, but seemed worried his parents may cut his evening short with an early curfew.
An onlooker at the screening of the new romantic-comedy 'The Rewrite' told The Sun newspaper: "Brooklyn was a surprise attendee and everyone was excited to see him arrive.
"But he very quickly sneaked off to a corner and had a very quick chat with his mum before going inside to watch the film."
Thankfully Victoria was lenient with her eldest son, allowing him to stay out - a move which didn't go unnoticed by other guests who thought it was a considerate decision to alert his parents of his evening plans.
The source added: "It was very sweet and great to see that the family are as close as ever and are always checking in on each other."

Simon Cowell has told this year's contestants on 'The X Factor' they must behave like One Direction.
The music mogul - who has returned as a judge on the ever-popular ITV show and is mentoring the Over-25s group - has stressed the need for them to be sincere during the show, citing the success of 1D and Olly Murs as examples to follow.
Cowell, 55, warned Jay James, Ben Haenow and Fleur East: "The audience can work out if you just want to be famous.
"If you're real and truthful, you shouldn't be afraid of that, don't put on a TV persona.
"Two artists who got it right were 1D and Olly Murs - they showed exactly who they were."
What's more, he encouraged the contestants on the show to be more vocal about the songs they performed and not to be afraid to stand up for themselves.
He said: "Don't be a puppet. If you choose the wrong song, you're out.
"You all have a real hectic workload but find an hour a day searching for ideas - you need to do that.
"Just work far ahead. Think about 1D and Olly - they were as tired as you'll be."
Following the pep talk, the trio of acts presented Simon with a cake to mark his 55th birthday.

One Direction do not intend to make a move into acting.
The band - which consists of Harry Styles, Niall Horan, Zayn Malik, Liam Payne and Louis Tomlinson - are currently preparing to release their concert film 'Where We Are', but it's been revealed they have no intention of following the likes of the Spice Girls - who made 'Spice World' - by doing a scripted movie.
Asked whether it's something the boys would ever consider, 'Where We Are' director Ben Winston told Digital Spy: "I don't think we've ever had conversations with the boys about it.
"I thought [the video for] 'Best Song Ever' was going to be very hard for them, and I remember when I pitched it to them it would be a really hard pitch - and even if they go for it, I don't know if they're going to have the ability to pull it off.
"I remember being on set in Miami gobsmacked by how brilliant they were and it sort of made me think, 'Wow, they really could do a movie like ['Spice World']'.
"But I never went to them with it, because I sort of feel that's not who they are."
Meanwhile, Julian Bunetta, who co-wrote some of the band's hit tracks including 'Best Song Ever' and new single 'Steal My Girl', recently revealed to MTV News that One Direction's new album will be a "musical rainbow".
He explained: "There is probably a whole bunch of stuff in between them ['Steal My Girl' and 'Fireproof'] that sound nothing like each other.
"So it's just one big One Direction musical rainbow; one song is green and one song is blue, one song is red."

Lydia Bright thinks she'll marry James 'Arg' Argent.
The 'Only Way is Essex' beauty - who split from her co-star in 2012 after he was unfaithful to her - admits they recently enjoyed a "massive holiday romance" while the show filmed in Ibiza and though she insists the future of their relationship is still uncertain, she loves him and thinks they are destined to be together.
Asked if she thinks they will marry, she said: "Yeah I do. I think he's The One. We'll probably end up together.
"[Do I love him?] Definitely. I would never say there isn't love between me and James, we've been through so much together and there has always been that chemistry, so we have a lot of love for each other.
"He tells me he loves me all the time but I've not told him yet. He knows I love him deep down."
Apart from Arg's infidelity, Lydia admits one reason why she ended their romance was that fame went to his head but she thinks he is now back to how he was before the show.
She told heat magazine: "The reason we broke up was all the fame went to his head and he lapped up all the female attention. He cheated on me a lot.
"He's like how he used to be [now] and that's why I'm falling for him again.
"I think that although 'TOWIE' was maybe the reason for us breaking up, it's brought us back together".
However, Lydia has warned her on/off lover he needs to "get serious" and mature if he is serious about getting their relationship back on track.
She said: "I love that James is funny and dopey, but if things are going to get serious he's got to grow up a bit."

Ben Hanlin "ruined magic" for his family.
The 'Tricked' star has confessed his family are no longer interested in watching magicians and illusionists because they've seen him perform so many tricks that it's not special or surprising anymore.
He exclusively told BANG Showbiz: "Friends and family are so used to watching me do stuff now that I haven't performed any tricks on them in years.
When I was a kid they would always get the tricks but now I've kind of ruined magic for them because they saw way more than most people."
The 25-year-old star - who advises people interested in getting into magic to visit specialist shops and keep practicing - also admitted he decided to make a career out of his passion when he realised he didn't want a "proper job".
He explained: "I found out I had a gift when I was 14 or 15. I spent time watching David Blaine and learning a few tricks. I'd sit and practice them at school and do a little bit of a trick there and learn it and then when I decided I didn't want to get a proper job I kept doing this really."
Ben Hanlin and Persil both believe that Dirt is Good and celebrated by creating some messy magic at a school in Staines.

Cara Delevingne has begun dating actor Jack O'Connell.
The model - who has been linked to the likes of Harry Styles and Jake Bugg in the past - met the 24-year-old on the set of forthcoming movie, 'Tulip Fever', in which they both star.
An insider told The Sun newspaper: "Jack and Cara get on really well. So far their relationship is very casual but she's a big fan of him."
The source continued: "They've been on a few dates and been seeing each other quite often but it's not yet serious.
"They met on the Tulip Fever set and hit it off immediately. They are both very busy all the time with work but they could make it work."
The 22-year-old bisexual model split from Michelle Rodriguez in May, while Jack - who used to appear in the teen drama 'Skins' - dated singer Tulisa Contostalvos in 2012.
Meanwhile, Cara - who has just unveiled her new capsule fashion collection entitled 'Cara Delevingne for DKNY' - claimed recently that self-confidence is a very attractive trait.
She explained to Glamour magazine: "Well it's not about what you wear it's about how you're wearing it.
"Self confidence is the most important component in fashion."

Demi Moore was a guest at the Kabbalah blessing of Ashton Kutcher and Mila Kunis's newborn baby.
The actress - who was married to Ashton, 36, from 2005 to 2013 - attended the Jewish-based ceremony in LA alongside her daughters Rumer and Tallulah.
An onlooker at the ceremony told The Sun newspaper: "Demi and her daughters congratulated the couple while having a quick hold and coo over the baby.
"It was great to see her doing so well and at ease with Ashton's new life as a father and fiance."
Demi, 51, also handed out presents - including an engraved picture frame and a personalised cashmere baby blanket - to baby Wyatt Isabelle, who was born on September 30.
Earlier this week, it was reported that Ashton wants "a more stable schedule" so he can be a hands-on father.
The 'Two and a Half Men' star wants to spend as much time as possible taking care of their baby girl.
A source told Us Weekly magazine: "He's been so helpful, chipping in with feedings, and he loves to hold the baby."
What's more, Ashton helped decorate the nursery at the couple's new $10 million mansion in Beverly Hills, which they have filled with stuffed animals.

Hans Zimmer and Christopher Nolan won't reveal any details about 'Interstellar' before it is released because they want audiences to be shocked by what they see.
The composer has created the score for the highly-anticipated sci-fi movie but he is under strict instructions not to reveal any plot details, because the director is determined to avoid internet spoilers.
Speaking to BANG Showbiz, Zimmer said: "Both Chris and I feel that we now live in a world where you're being given everything on the internet, you're given all these little bits of information and you can't ever come at something and be amazed and surprised anymore and take it in as an experience. The idea of actually having an experience is nearly gone and we work really hard on these films we certainly put the hours in and we try and make it as great as possible and we don't want to dilute it beforehand."
The 57-year-old German musician has also delayed the release of the soundtrack because he wants people to hear his score for the first time in conjunction with the movie.
He explained: "The normal form is you release the soundtrack two weeks before the movie comes out but this time I'm not going to do that I'm going to release it two weeks after the movie comes out because I want the majority of people to hear the music for the first time with the film. I want them to go and hear it on big speakers, I don't want them to hear it on their little computer speakers. It's not why I get up in the morning."
Zimmer previously collaborated with Nolan on 'Inception' and 'The Dark Knight' trilogy and he considers the British movie maker to be one of the most impressive directors he has ever worked with.
He said: "Working on 'Interstellar' was the best experience I ever had on a film, so I suppose that would mean he's my favourite director to work with. It was so great I'm actually going to take some time off from movies now ... We just work really good together and we have very similar sensibilities and I think the most important thing is that we're very supportive of each other. You sit there in this weird vacuum of having to make this movie and having all this pressure on you and we just try and protect each other from getting it wrong."
Zimmer is performing his first-ever concerts in the UK at the Eventim Hammersmith Apollo this Friday (10.10.14) and Saturday (11.10.14).
'Hans Zimmer Revealed' will feature music from his entire career including the scores from movies such as 'Gladiator', 'The Lion King', 'The Amazing Spider-Man 2' and Nolan's Batman franchise.

Nick Oliveri will perform with Queens of the Stone Age later this month.
The 42-year-old bassist - who was fired from the band in 2004 - is supporting his old group at The Forum in Los Angeles on October 31 and his former bandmate, singer Josh Homme, has asked him to join them for the encore.
Nick said: "Josh asked me to do six songs with Queens, like an encore set. A reunion, but not a reunion.
"I'm going to get up and play some bass and sing some songs at the end of the show. It should be interesting."
The rocker admitted he has been keen to play with the 'Feel Good Hit of the Summer' rockers many times since his departure and suggested he would like to do so again in the future.
Asked if he will play more shows with the band, he told NME magazine: "That's pretty much up to Josh. It's his band.
"I put myself out there a few times in the past 10 years. I'd go and see them play and say, 'Hey man, I'm here! Do you want me to sing a song?'
"I stopped asking after a while and then he asked me.
"It's not up to me, is what I'm saying."

Melissa Joan Hart reportedly locked her youngest child in her car.
The 'Melissa & Joey' actress, who has three sons, Mason, eight, Braydon, five, and two-year-old Tucker with Mark Wilkerson, was forced to call a locksmith to break into her red GMC Denali after she accidentally closed the door with her keys and Tucker inside while she was running errands in Los Angeles on Tuesday (07.10.14).
The 38-year-old star looked relieved when the AAA [American Automobile Association] arrived at the scene and quickly reunited her with her little boy, according to gossip website TMZ.com.
An eyewitness also told E! News: "No harm was done and Tucker was rescued. AAA was able to open the door quickly."
Hours later the blonde beauty admitted she isn't immune to making mistakes on Twitter, writing: "If you're not making mistakes, then you're not doing anything. I'm positive that a doer makes mistakes."
The former 'Sabrina, The Teenage Witch' actress recently confessed she prefers having romantic dates with her husband during the day, as she is usually exhausted at night from looking after their sons.
She said: "I feel like nighttime, you pick fights, you're exhausted. So instead, lunch time to me seems like you're kind of in the middle of the day and have energy and can talk things out without getting emotional. It works so much better for us."
