She's taking things as they come.

Kourtney Kardashian stepped out with son Mason yesterday, and the reality star was glued to her phone the entire time. We bet she was on the line with boy toy Younes Bendjima! She's got to keep in touch with him while she's busy with the kids, because she's not ready to introduce him to her brood just yet.

"Kourtney is having a ball with Younes, he’s exactly what she needed after the hell she went through with Scott [Disick, 34] — he’s like a breath of fresh air. They’re keeping things pretty casual still, and just having fun, neither of them want to be in a a serious committed relationship right now, so it’s perfect," a source dished to Hollywood Life.

"Younes hasn’t met the kids, and Kourtney doesn’t want to introduce him to them at this stage, but if things were to become more serious between them then obviously she would. Right now though, Kourtney is just enjoying letting her hair down, and being someone other than just a ‘mom.’ Dating Younes has given Kourtney a much needed new lease on life, she didn’t realize just how much all the drama with Scott had been bringing her down, until now," the source added.

The Lord, meanwhile, has been laying relatively low and has taken a break from partying and womanizing. We caught him at the gas station fueling up his new Rolls Royce yesterday, and we were shocked at how skinny he's gotten. We bet he's lost his appetite thinking of Kourt moving on for good!
