Looks like there aren't any pre-wedding jitters here!

Kanye West 'never looked happier' at a book party with pals yesterday evening.

E! News has learned that the rapper was with a close group of friends to celebrate businessman Ben Horowitz's latest release, The Hard Thing About Hard Things: Building a Business When There Are No Easy Answers.

An eyewitness tells us that while West is normally more downtrodden at such events, he was 'talking to everyone and was in such an incredible mood.'

The onlooker added, 'I've never seen him smile more. You could tell he was just really happy to be there.'

Guests at the bash enjoyed snacks from L.A. eatery Lucques and VeeV cocktails.

And aside from supporting his friends' ventures and wedding plans, it looks like West is also working in the studio with rapper Tyga.

Tyga just revealed during a visit to Power 106 radio station that Yeezus will be executive producing his upcoming LP, tentatively dubbed The Gold Album: 18th Dynasty.

'Kanye executive producing that, so it's gonna be a crazy album,' he said on the air. 'It's just good to have people like him [and] Wayne. They're all these people I grew up on. To really be mentored by the greats, it just puts you in that running.'

After the book party, Tyga was both spotted having a boys' night back at West's home with several other friends, X17 Online reports.

'Kanye wanted to have a boys' night before he and Kim [ Kardashian] get their wedding license. It wasn't a full-blown bachelor party...just a chill night with friends.'
