Kim Kardashian shocked her BFF Tracy Romulus by gifting her a $100,000 matte black Tesla Cybertruck for her 45th birthday this week.

The SKIMS founder, 44, shared footage of herself surprising Romulus with the new car on Thursday.

Kim parked the luxury vehicle in the driveway of her $60million Calabasas mansion and told Romulus to ‘turn around.’

Once Romulus spotted the car, which had a large red bow pinned to the hood, she exclaimed: ‘What! Kim are you f***ing serious?! Are you nuts? Are you crazy?’

Kim, who stood nearby laughing and smiling, told Romulus that it was her birthday gift.

‘Shall we take your car tonight,’ Kim asked, before embracing her excited pal in the driveway.

Referring to Kim as her ‘crazy, over the top [best friend],’ Romulus uploaded a blurry image of the Cybertruck to her own Instagram Story.

Over top of video of her and Kim gawking at the Cybertruck in the driveway, Romulus wrote: ‘I literally have no words… @kimkardashian… no one does gift giving like you… this is so over the top crazy… only you… i love you…’

Kim and Tracy looked to be gearing up for a girls’ night out in Los Angeles.

They coordinated for Tracy’s birthday by wearing matching black leather trench coats.

Kim made the rare move of rocking Converse sneakers as she is still recovering from a foot injury.

Along with being among Kim’s closest confidants, Tracy works closely with the billionaire.

According to her LinkedIn, Tracy has been the Executive Vice President, Communications at SKIMS, Kim’s successful shapewear line, since 2017.

Kim’s custom Cybertrucks, one black and one silver, could be seen parked in the background of the Instagram Story clips posted Thursday.

She added her first Cybertruck to her car collection in February 2024, followed by a sleek matte black version in May.

Referring to Kim as her ‘crazy, over the top [best friend]’ Romulus also shared footage of the big surprise to her own Instagram on Thursday

The reality TV star is a longtime Tesla fan and recently introduced fans to her $30,0000 Tesla bot.

She posed for a bizarre Instagram photo-shoot with the droid, with one image showing her holding hands with it in a Cybertruck.

However, she was forced to deny accusations that she was being ‘paid’ by Tesla founder Elon Musk.

A rep for Kim told The New York Times last month that the SKIMS founder was not financially compensated for the photos.

Kim’s surprise for Tracy comes amid a heavy promo push for SKIMS’ new winter lingerie line ahead of the holidays.

On Wednesday, Kim shared new sizzling campaign snaps that showed her straddling a fur bench in a skimpy bras and underwear.

The sultry Winter Heat collection includes thong underwear, knit sweaters, bralettes and a plethora of other fashion basics.

Products range in price from $16 for knit socks to $128 for an oversized hoodie.

Last week, Kim celebrated the opening of the new SKIMS flagship store on New York City’s Fifth Avenue.

It marked the brand’s sixth brick-and-mortar store in the United States.

Other locations include: Washington, D.C., Aventura, Florida, Austin and Houston, Texas and Atlanta, Georgia.

During the NYC grand opening on November 12, Kim dished on her and her family’s famously extravagant Christmas Eve bash.

The lavish soiree is held every year at one of the Kardashian-Jenners kids’ homes.

Kim hosted in 2023 and turned her Calabasas mansion into a winter wonderland.

She also invited a slew of celebrity guests, including 13-time Grammy winner Babyface, who performed for lucky attendees.

But Kim told Vogue that they’ll be having a more ‘intimate’ family gathering this year.

‘We’re doing a really low key Christmas Eve party this year just because we have a lot of construction going on,’ the SKIMS founder, 44, revealed.

The mom-of-four is currently renovating her $60million Calabasas mansion while her sister Khloe is also renovating the house she purchased right next to their mom Kris Jenner’s in Hidden Hills.

She continued: ‘We’re doing a family intimate one that I’m really excited about – still dressing up to the nines because that’s what we do.

‘We’ve had some legendary Christmas Eve parties and they’re just beginning. Our kids love them and now all their friends want to come,’ she told the outlet, adding: ‘It’s such a fun tradition.’
