Friday was a big day for Kim Kardashian West, to say that least. Her son Saint said the word “Dada” for the first time.

“He said ‘Dada’ today, three times, and I was like, ‘What?,’ ” the reality star, 35, told E! News at MGM Grand’s Hakkasan in Las Vegas on Friday. “Kanye [West] was so excited. He was like ‘I told him to say that.’ I was like, ‘I just really wanted him to say Momma first.’ “

The excitement continued into the evening, albeit in a different state, as Kardashian West headed to Nevada to celebrate the bachelorette party of one of her friends in Sin City.

Kardashian West arrived at Hakkasan at 1 a.m. local time on Saturday with her squad, which included the bachelorette, as well as pals Larsa Pippen — wife of NBA legend Scottie Pippen — and E! News host Maria Menounos.

The Keeping Up with the Kardashians star looked stunning in a black figure-hugging dress while hanging out in the club into the early hours of Saturday morning.

“I’m definitely to my goal weight,” she told reporters, referencing the 70 lbs. she lost since giving birth to Saint in December, adding that she’s “definitely down way more than I expected.”

Since having her son Saint, Kardashian West has been a staunch supporter of the Atkins diet.

“The Atkins diet is so easy to me, because there are so many sweets and treats and stuff to keep you satisfied along the way,” she said, adding that her husband is “super into working out,” giving her a support system.

On Saturday morning, Kardashian West wasn’t completely thinking about her diet, sipping on Veuve Clicquot champagne with her group and taking selfies with friends and fans that clamored to be near her VIP table.

While listening to the sounds of Fergie DJ, Kardashian West beamed, trying to shift much of the attention onto her bachelorette friend.

“I’m so excited to be back at Hakkasan,” she told the crowd, encouraging them to party for her betrothed friend.

At 2:30 am, the reality star and her crew left the club.
