Kendall Jenner concluded her birthday festivities with a masquerade-themed dinner with her family and friends on Sunday.

The Keeping Up With The Kardashians star, who is also a model and Pac Sun clothing designer, shared a series of pictures on Instagram of her guests wearing a variety of feathered masquerade masks on the day she turned 18.

The location for her private birthday dinner was not disclosed, however, X17Online shared a video of the Kardashian and Jenner clan along with Kanye West exiting the secret venue.

In the clip, Kendall's newly separated ponytailed father Bruce Jenner enters his own vehicle while her mother Kris Jenner drives off in a separate car. Also, Khloe Kardashian is seen wearing a pink mask, Kylie Jenner a blue one and Kim Kardashian has star stickers on her forehead.

Jenner was also given a Great Dane puppy by her stepbrother Rob Kardashian ahead of her 18th birthday two weeks ago. She shared a picture of her early birthday present via Instagram on Oct. 22.

"Happy early birthday to me!!! My new little princess! thank you @robkardashian you're the greatest," she wrote. The comment was attached to a photo of the pup she named Blu, who was seen sleeping next to a pink blanket.

Jenner was snapped by paparazzi the next day carrying the pup around in her arms as she stepped out in Los Angeles with friends.

Her family later surprised her by renting out Six Flags Magic Mountain in Valencia, Calif. on Oct. 29. Her older sister Kim shared two personal videos on Keek videos from their day trip.

In Kim's first video, she discussed how lucky they were to have access to rides without waiting on lines.

"We're here for Kendall's birthday party and we rented out Magic Mountain," Kardashian says in the clip. "No one else is in the entire theme park but us and the people there to greet us."

In the second video, she took her fans along on her roller coaster ride. She is seen sitting next to her new BFF, video model and dancer Blac Chyna.

"I hope this isn't too scary," she says in the short clip before the ride nosedives, adding, "we better not drop our phone!"

The video ends with Kardashian and Chyna screaming hysterically.
