Chanel West Coast and Ray J seemed ready to gather round a campfire this weekend … ’cause he gobbled up snacks, and she told ghost stories on our “TMZ After Dark Tour.”

The two stars hosted the Hollywood tour on Friday and Saturday nights, respectively … and, Chanel got the group into spooky season early when they drove past her old apartment building in the City of Angels.

Chanel swears it’s haunted … and, she got out of there as quick as she could back in the day!

While riders got the usual fun-filled tour — with drinks, dancing and good vibes all around — they also stopped by Crumbl … a popular dessert shop that celebrated its eighth birthday this month!

Ray J hopped off the bus to get his cookies from the national chain — which boasts more than 1,100 locations — and he tried out the Milk Chocolate Chip Cookie, the Original Pink Sugar Cookie, and the Cornbread Cookie off the Secret Menu … and he crushed these cookies FAST!

Here one minute and gone the next … and, don’t forget … there’s a weekly rotating menu of classic fan favorites and delightful new concoctions!
