Kim Kardashian Engaged

Kanye West pulled out all the stops when he proposed to Kim Kardashian last night ... paying the orchestra members a relative fortune ... all while cameras were rolling.

A member of the orchestra tells TMZ ... she was paid 4 times what she usually gets for such a gig -- members snagged up to 1k each.

She says no one got wind of Kanye's plan until 2 days before the event. A contractor reached out to a bunch of musicians in the area. But here's the thing ...The orchestra members kept the secret for a full 2 days. They did sign non-disclosure agreements, but you know how that works ...

The woman also tells us ... multiple cameras were rolling during Kanye's proposal, so there's plenty of material for the Kardashian reality show. We're told Kanye has final approval over whether it goes on the show or not.

The engagement comes 4 months after Kim and Kanye's daughter North was born -- and 18 months after they went public as a couple.

Monday was Kim's 33rd birthday. This will be her third shot at "til death do us part," and Kanye's first.

BTW -- In case you're interested, it costs $35k to rent out the field. We're guessing he can afford it.

Kanye West has figured out a new way to idolize baby mama Kim Kardashian -- he's enshrined her on his t-shirt.

The rapper was spotted in Seattle yesterday wearing the shirt with Kim's face on it -- shortly before kicking off his Yeezus tour -- and he couldn't help but smile.

Which raises the question ... would you wear a t-shirt with your S.O.'s face on it? Sound off in the comments.

If you think Kanye West is proprietary about Kim Kardashian's ass, think again, because he clearly believes it's awesome and is glad she's sharing it with the world.

We're told his response when he saw Kim's Instagram pic was that he loves having a hot chick.

Kanye retweeted the link to the photo and wrote, "HEADING HOME NOW." In case his message isn't clear ... it was put to us this way ... he's proud of it because it's his girl.

Kanye West -- into sharing.

Kim Kardashian's gargantuan ass is back in working order ... and last night, she let the world know ... with a backside selfie on Instagram

It's the first butt-selfie Kim's taken since giving birth to Kanye West's baby North back in June.

Kim's been on a serious sexuality kick lately -- on the most recent episode of her reality show, she talked about wanting to pose NAKED asap ... saying, "As soon as I get in shape, the first thing I want to do is Playboy or some nude shoot. I just wanna walk down the street fully naked."

Looks ready to us.

Kanye West and Kim Kardashian just arrived at San Francisco International Airport, en route to Paris ... and they did exactly what we said they would do ... avoid the paparazzi at LAX.

Kim and Kanye took off from the Van Nuys Airport a few hours ago and landed at SFO. They're transferring to a commercial flight that will take them nonstop to Paris.

As we first reported, Kanye has been advised by his reps NOT to fly out of LAX, because they don't want another confrontation with photogs while his criminal battery case is pending.

Problem is ... the reps didn't bank on photogs showing up at his house early this AM ... resulting in yet another confrontation.

The paparrazzi at SFO -- not ours -- also shot video of Kanye and Kim, and much like this morning ... they're clearly getting under Kanye's skin.

Also, note to all paps -- if nothing else, pronounce the guy's name right. It's KAHN-YAY.

Kim Kardashian and Kanye West's $11 million love shack is still under construction -- it has been for months -- and Thursday they put some pressure on the contractors ... by personally inspecting the quality of their work.

K&K dodged piles of scrap lumber and plywood as they did a walking tour of the 10,000-square-foot Italian-style villa in Bel Air, CA ... making sure the builders didn't leave out any details... like the bowling alley. Or the hair salon. Or the gym. Or the baby's nursery.

Hopefully the walls of the house are really, really thick ... 'cuz Kanye likes to yell. And everybody knows ... if the baby don't sleep ... nobody sleeps.

Kim Kardashian finally showed her face in public after birthing baby North West -- surfacing at an L.A. medical facility Wednesday -- and giving us a glimpse at her post pregnancy bod ... sorta.

These are the FIRST photos of Kim and Kanye West with their daughter since KK popped back in June, and everyone looks happy and healthy. Hell, even Yeezy was smiling as they walked into the doc's office ... with a nanny-assist, naturally.

No shot of North's face though ... she was fully covered in a car seat.

Mama K was all top secret too -- concealing her figure under a baggy button-down with another shirt tied around her waist and famous cheeks ... for extra coverage.
