"He's seen her a few times in L.A. and thinks she's really hot," a source tells Us. "He's definitely interested and seeing where it goes." (Last month, Sandberg posted a gorgeous Instagram photo of herself working with Sanctuary Clothing.)
The new romance comes six months after Disick, 32, and Kardashian, 36, ended their nine-year relationship. Disick was spotted getting cozy with his ex Chloe Bartoli in the South of France at the time. (Disick and the Keeping Up With the Kardashians star are parents to three children: Mason, 5, Penelope, 3, and Reign, 12 months.)
Disick has had a tough time since the breakup. Us Weekly exclusively confirmed in October that he entered rehab for drug and alcohol addiction. The star also broke down in tears over the split in a recent episode of KUWTK.
Kardashian, meanwhile, has also been enjoying the single life. Us broke the news last month that the mom of three recently hooked up with Justin Bieber.
"Justin bragged to friends recently that he has been hooking up with Kourtney Kardashian," an insider previously told Us. A second source added, "Every time Kourtney and Justin are together they’re extremely flirtatious. They text each other all the time."
It appears, though, that Bieber, 21, has moved on. Over the weekend, he posted an Instagram photo kissing Hailey Baldwin.
