This romance shows no signs of slowing down!

Kylie Jenner spent the weekend on the East Coast with new boyfriend Travis Scott, and the reality star made sure to invite sister Kendall and all her famous pals to the rapper's birthday party in NYC on Saturday. The LipKit mogul dressed down for the occasion in spandex pants, a Reebok windbreaker, and Vans, and her smile says it all. This is what revenge looks like!

Apparently, the new couple were all over each other inside the bash, and earlier in the weekend, it was the same when the Keeping Up with the Kardashians star accompanied the "All The Way Up" crooner to a performance at Bentley University then partied the night away with him at a Boston nightclub.

We wonder what her ex Tyga thinks of all this? He's probably scrambling to win her back, but this time around, it seems like she's finally moved on. He should have put a ring on it when he had a chance! Now he's lost his sugar mama and is going to have to figure out how to pay his own bills and stay out of trouble with the law all by himself. Poor T-Raww!
