Cassie was out and about in NYC, flashing her smile and soaking up the good vibes ... while her ex Diddy is stuck in a whole different reality -- lonely and behind bars in a notoriously grimy Brooklyn prison.

The singer looked at ease as she headed to the trendy hotspot "Left Bank" for an al fresco dinner Wednesday ... where the fun continued as she appeared to excitedly show her pals something on her phone at the dinner table.

While we can't say for sure, it’s a safe bet that Diddy came up in conversation at some point, especially since he was sensationally denied bail on the very same day.

ZB says he was speaking strictly musically, and wasn't cosigning any of Ye's other beliefs ... before adding he loves Taylor's music too -- and simply screwed up in his post.

Germanotta says he thinks the whole concept of voting for people is a bit odd ... but, even though he admits he finds DJT abrasive, he rattles off a series of Trump policies that align with his own views.

NOT GIVING UP

Per Agnifilo, he's hoping to get Diddy's case to trial sooner rather than later to "minimize" the amount of time he'll have to spend behind bars.

He also called out the rapper's prison conditions as "inhumane" ... though, the lawyer said Diddy is "ready" and "focused" ahead of the trial.

Diddy's fight to get out of jail has stopped in its tracks ... 'cause after arriving at court today to appeal a judge's ruling he shouldn't be released on bail, he's headed back to the detention center.

The rap mogul arrived at a federal courthouse in New York City Wednesday ... where his sons, Christian and Justin, came out to support their dad -- though ultimately, the judge in the case decided not to grant Diddy bail.

Diddy Judge Throws Out $100 Mil Judgment In Battle With Michigan Inmate

Diddy's got a small reason to smile despite being behind bars in federal custody ... a judge just set aside the $100 million default judgment in his Michigan sexual assault lawsuit.

The embattled rapper scored the legal win during a motion hearing Wednesday ... where one of his attorneys, David Fink, convinced the judge to set aside the massive judgment because inmate Derrick Lee Cardello-Smith -- who claims Diddy drugged and sexually assaulted him at a 1997 Detroit party -- failed to prove he effectively served the lawsuit in accordance with Michigan law.

Judge Anna Marie Anzalone also scrapped the temporary restraining order stopping Diddy from selling off any assets to cover damages ... noting Diddy has a likelihood of winning the case on statute of limitations grounds because Cardello-Smith's claims date back to an alleged incident in 1997.

DAYS BEFORE ARREST
TMZ.com

Prior to his arrest Monday night, Diddy hit the NYC streets and interacted with fans ... days before ending up in federal custody.

Check it out ... Diddy smokes alongside a fan, named Chris Dayes (Christian Daigle), while listening to a song off a cellphone. Diddy, dressed in sunglasses, a baseball cap, and a Prince sweatshirt, looks totally at peace ... even though a grand jury indictment loomed over his head at the time.

Diddy I Promise, No Female Visitors ... If You Let Me Out on Bail

UPDATE

12:16 PM PT -- Federal prosecutors have fired back, responding in court documents that claim Diddy is just too dangerous to be out walking the streets -- no matter what the rap mogul's lawyers say or do.

As the prosecutors point out ... Diddy repeatedly obstructed justice during the investigation -- not to mention, is still an alleged flight risk. They claim Diddy is capable of coercing witnesses to comply with his demands.

They also voiced concerns that Diddy could consume drugs or throw his so-called "freak parties" if out on bail ... despite the rapper's promise he wouldn't have any female visitors.

Diddy is taking another swing at getting out on bail, and he's upping his offer to the court -- declaring he will forgo contact with almost all women while he's out.

In docs, obtained by TMZ, Diddy's legal team says if he's released on bail, the security company that keeps a log of all visitors to his Miami Beach home, will hand over those logs to the government nightly in order to be fully transparent about who Diddy is contacting. They also say Diddy will limit all visitors to family, property caretakers and friends who are not co-conspirators in the federal indictment.

Specifically, they say Diddy will restrict female visitors ... with the only exceptions being family members or mothers of his children.

Boosie Badazz Like Diddy, All Celebs Fly In Women He's Just Freakier!!!

Boosie Badazz has come to Diddy's defense after the Bad Boy mogul was denied bail ... an expected outburst for him at this point -- but his reasoning may still surprise you!!!

Diddy was charged with sex trafficking, racketeering and kidnapping, and pled not guilty -- but the way Boosie sees it, those "Freak Offs" have been twisted to demonize common celebrity behavior.

For what it's worth he also appears to frown upon the surveillance footage of Cassie's assault ... suggesting Diddy needs professional help.
