Khloe Kardashian waved bye-bye to her boyfriend Tristan Thompson in Cleveland, Ohio and hitched a ride on airplane to Los Angeles to be home in time for the birth of her brother Rob Kardashian's baby girl on Thursday morning.

The 32-year-old was outfitted in a black leotard, black hoodie with a colorful hood and black sneaks! Even though she's on the go -- Khloe is still tres chic!

We're glad she hightailed it out of the midwest so she could be there for the birth of her niece, who was born on Thursday morning. Blac Chyna and fiance Rob Kardashian welcomed daughter Dream Renee via C-section at Cedars-Sinai hospital in LA, E! News confirmed.

The little one arrived at 9:18am and weighed 7 pounds 5 ounces. The newborn joins Chyna's son King, 3, with ex Tyga. The video vixen's mom Tokyo Toni was by her side, as was future mother-in-law Kris Jenner and her boy toy Corey Gamble. This is the first child for the couple, who became engaged in April and announced they were expecting in May.

After seeing Dream, Khloe tweeted her praise over the newborn, writing, "My new niece is absolutely stunning!!! So thankful I was able to land in time to witness this miracle happen! Praise God!"
