Clearly Kourtney was looking for some validation after the holidays because on Monday the three-time mom posted a flashback swimsuit photo of herself from seven years ago.

But she wasn't the only one posting racy Instagram pics yesterday -- so was Bieber! While we’re a bit shocked the 21-year-old popstar would be hooking up with the oldest Kardashian — we get why the mom would want to throw down with the “Sorry” singer. Just look at the shirtless Instagram he posted on Monday. Dude’s hot!

But were Kourtney and Justin really "dating?" In a trailer for this Sunday’s episode of Keeping Up With the Kardashians, the oldest Kardashian says she’s “not a dating person.” But apparently she IS a secretly-hooking-up-with-Justin-Bieber-for-months kind of person!

On the upcoming episode of KUWTK, Kris Jenner, who is dating boytoy Corey Gamble, says to Kourtney, ”I’m just telling you to keep an open mind. It would be kind of cool if you … went on a date. Kourt says, "I'm not a dating person. I did the dating thing before Scott for, like, a minute, and it was so not for me."


Scott and Kourtney split in July after he got caught canoodling with his ex-girlfriend Chloé Bartoli in the South of France.

In the upcoming episode, the 36-year-old mom of three says, ”I just got out of a nine-year relationship. I think the last thing I probably need is anybody in my life."

But it appears as if she has somebody — or several somebodies! Before Christmas, Kourtney was snapped dining with Diddy’s son Quincy Combs. And of course — there’s her relationship on the down low with the Biebs.

Meanwhile, bad boy Scott Disick showed his soft side when he posted an adorable photograph of daughter Penelope sleeping soundly — and captioned the sweet snap, "dream girl."

Kourtney Kardashian’s estranged partner shared the pic on Instagram on Monday night. Here, Penelope is asleep, but still wearing her lil’ denim jacket and a pair of black leggings. Her lil’ tum poking out is too cute! 
Was Scott trying to win daddy points with Kourt by posting this?

We are glad to see Scott making some time for his family after his reported relapse earlier this month, but we’ve got our eyes out for him as he’s set to host a Las Vegas New Year's Eve bash at 1 Oak at the Mirage Hotel & Casino from 9 p.m. on December 31. Probably not the best call for a man who just went to rehab!
