Demi Lovato was a sight to see arriving at the second night of Paris Hilton's three-day wedding celebrations this Friday.

The 40-year-old bride, who married dashing businessman Carter Reum on Thursday, has rented out the Santa Monica Pier to set up a sprawling 'Paris World' carnival. 

For the big event Demi, 29, who has come out as nonbinary and uses 'they' pronouns, was wrapped up in an eye-popping faux fur coat.

The pop act was given plenty of importance at the wedding function, being warmly greeted by core members of Paris' family.

Mother of the bride Kathy Hilton was seen sharing an embrace with Demi, as was sister of the bride Nicky Hilton Rothschild who was also matron of honor. 

The Sober singer was modeling a pair of lime green cat-eye sunglasses that matched the coat, despite its being nighttime.

Demi accentuated the look with jewelry including a large ornate ring, a glimmering necklace and a pair of earrings made to look like Saturn.

The colorful pieces of the outfit were clashed fashionably against a white top and black cutoff trousers, plus metal-studded black platform shoes.

While sauntering around the event Demi was also seen to be carrying a large black handbag that was covered in faux fur.

Demi took the show to social media, pulling a pout for a selfie and tagging the glam squad that helped put the look together.

Over the course of Demi's Insta Stories fans could also catch a glimpse of the bride and groom cheerfully enjoying one of the rides.  

Paris and Carter's rave-inspired outdoor celebration on Friday night proved to be a major contrast to their elegant, polished wedding ceremony on Thursday.

They tied knot at Paris' late grandfather Barron Hilton's sprawling Bel Air estate. 

Paris shared an intimate look at the ceremony and reception, which served as just the first events in the couple's multi-day wedding celebrations, which will continue into the weekend.

She modeled four different wedding gowns while celebrating with a host of A-list guests, including Kim Kardashian, Nicole Richie, SLOT ONLINE MUDAH MENANG Emma Roberts, and Ashley Benson. 

Lovato was on hand at the reception, singing I Will Always Love You as the first dance song.

Kim Petras also contributed her musical prowess to the occasion.

'They were incredible. It brought so much emotion and love to the event,' Paris said of Demi.

Paris and Demi have been friendly since 2017, when the socialite made a cameo in Demi's Sorry Not Sorry music video.

Most recently, Demi appeared on Paris' Netflix show Cooking With The Paris.
