Khloé Kardashian and Tristan Thompson Make Relationship Official as She Promotes Her New Denim Line in NYC

It’s been a pretty eventful week for Khloé Kardashian and it just got even better.

Just a few weeks after stepping out publically with NBA star Tristan Thompson, sources confirm to ET the duo is now “full-on dating.” “They’re taking it slow, day by day, but are having so much fun together,” the source continued.  “It’s still the honeymoon stages and they both have a huge crush on each other.”

As for Kardashian’s estranged husband Lamar Odom, sources close to Kardashian say he is 100% out of her life. “Lamar is out of her life completely,” the insider insisted, “No animosity there. She still cares about him, she still wants him to be safe, but it’s over.”

While Kardashian is waiting for her divorce from Odom to be final before things get really serious with Thompson, he’s already got her mother’s stamp of approval. “I have [met Tristan], he’s a wonderful guy,” Kris Jenner told ET. “I have met him and he’s great.”

“He’s the nicest, sweetest guy,” a source said. “He comes from a very strong family and has a tight circle of close friends. He really isn’t into the ‘celeb scene’ and does his own thing.”

At the same time that Kardashian’s love life is heating up, so is her career. Kardashian headed to NYC after a PDA-filled trip to Miami with Thompson, to promote her new line of denim, Good American. The line won’t hit stores until next month, but Kardashian promises the perfect pair of jeans for women of all sizes.
