Khloe Kardashian says her mom had some advice for her dating game … and, it’s that if you want to get ahead in a relationship — ya gotta give a little!

The reality television star discussed a moment where Kris Jenner left her “mortified” … explaining she once brought some friends over — and, they talked about why a guy she was seeing wasn’t getting back to her.

Khloe says Kris asked her how many dates she’d been on with this guy — an L.A. basketball player who Khloe doesn’t name — and, after telling her mom one or two, KJ offered some NSFW unsolicited advice.

Blake Lively‘s remembering her former costar Michelle Trachtenberg … saying she always gave 200% effort and she always stood up for what she believed in.

The actress took to Instagram just hours after it was announced that Michelle had passed to pay homage to the star … sharing a photo of their first day meeting and talking about her former “Gossip Girl” costar.

Blake says she brought an electricity to every room she walked into … always living life to the fullest — laughing hard at jokes, taking on authority head-on when she saw injustice and added she was proud to be an actor even when the industry can be difficult.

Lively also mentions a specific detail … saying Michelle always wore a caramel scented lip gloss — a scene she now associates with Trachtenberg clearly.

Lively tells her fans not to take any chance to see old friends for granted … because tragedy can strike when you least expect it — and, you’ll always treasure time with loved ones.

Blake ends her post by saying the world lost a “deeply sensitive and good person in Michelle.”

Trachtenberg and Lively worked together on multiple episodes of “Gossip Girl” … with Michelle playing Georgina Sparks — a troublesome, hard-partying friend of Blake’s Serena Van der Woodsen.

While originally conceived as the series’ main antagonist, Michelle’s character had a shorter run on the series of just 28 episodes — though her character ultimately found her way into the good graces of the protagonists’ inner circle.

Michelle was pronounced dead early Wednesday morning after police and paramedics responded to a call for a woman in cardiac arrest, and found Michelle unresponsive, law enforcement sources told us. She was pronounced dead on the scene.

Another source told us Michelle received a liver transplant in the past year … unclear if that played a role in her death, but we’re told cops are looking at this as a natural death.

Ed Westwick — another of Michelle’s “Gossip Girl” costars — also posted for Michelle Wednesday … saying he was sending prayers after her passing.

Trachtenberg is also known for her roles in “Buffy the Vampire Slayer,” “17 Again,” “Inspector Gadget,” “EuroTrip,” “Mercy” and many more.

Michelle was 39.

New details have emerged in the death of actress Michelle Trachtenberg … her mother tragically discovered her daughter’s body in bed Wednesday morning, just months after her liver transplant, TMZ has learned.

Law enforcement sources tell TMZ … Lana entered Michelle’s Manhattan apartment, only to find her unresponsive, lying on her back in bed — Lana then called police and paramedics, who pronounced Michelle dead at the scene.

We’re told Lana last saw Michelle alive at 10 PM Tuesday, and she was clearly active despite her health concerns — the “Gossip Girl” actress was even out with friends last Thursday night at Sartiano’s in NYC.
