It was their first family vacation with their three-month-old daughter Stormi, but Kylie Jenner and Travis Scott treated it more like their honeymoon. The couple is getting along better than ever, and sources revealed to Life & Style that the "Goosebumps" rapper and the reality star are engaged!

Kylie, who rocked a ring on that finger on Instagram this week, is now planning a luxe beach wedding that she hopes will be "the most extravagant Kardashian wedding of all time," the source added. And with a $10 million price tag, Kylie is not sparing any expense. Watch the video above for all the exclusive details on her upcoming nuptials and her new sparkler.

"She’s looking to spend about $10 million and have the wedding of the century," the insider said. "She’s even joked that she wants to outdo Prince Harry and Meghan Markle’s big day!" Finding a location that tops Windsor Castle might not happen, but the couple did check out massive mansions in the Turks and Caicos during their recent getaway. "The Eden Rock hotel in St. Barts is another possibility," the source explained. "Kylie would pay to book the whole hotel."

And there's no denying the 20-year-old has the budget for it thanks to her lip kit empire. Kylie, whose current net worth is estimated at over $300 million, is on track to become a billionaire by the age of 25. To put her wealth into perspective, in the last two years, Kylie Cosmetics has done $420 million in retail. In comparison, Bobbi Brown took 25 years to reach the billion-dollar mark, while Lancôme hit the milestone in 2015 after 80 years in the beauty business. Not too shabby…

It's no surprise that her older sister Kim Kardashian jumped on the beauty bandwagon as well — but Kylie reassures fans there is no competition between the siblings. "We’re both really proud of each other — and our brands are also completely different… just visually… there’s definitely enough room for the both of us," she told WWD. "I want to keep building it and just show people what I can do on my own."

For his part, Travis is worth $8 million, plus he can't get enough of his baby mama. "They've both matured and travis has seen a whole new side of Kylie," a source told Life & Style. "He's crazy about her!" Congrats to the happy couple!
