Nick Jonas once went on a date with someone who'd researched him online beforehand.
The 22-year-old singer admits he's been on a number of bad dates in the past but one in particular stands out to him because the lady knew too much about him and he felt awkward when she fired questions at him.
Speaking in the November issue of Cosmopolitan magazine, he said: "Well, there was a few [dates] where, like, alcohol was involved and it just got really bad. Those weren't necessarily the worst dates.
"The worst dates are when people, like, know more about me than is comfortable."
He elaborated on one particular time: "She just starts asking me questions that you wouldn't know unless I told you, but she knew from wherever, from online or something. I don't know. It was just very odd."
The hunky star has three vital traits he looks for in a woman before he starts a relationship with her.
When asked what he looks for in a partner, he said: "Honesty, sense of humour, and good times."
However, he admits he can't stand going on dates with people who spend all of the time on their phone, rather than enjoying the romantic occasion.
He added: "No phones. Put your phone away. That's, like, every date, even years into a relationship. Stop texting. Pay attention to what's going on right now."
Meanwhile, Nick is currently dating his brother Joe Jonas' ex-girlfriend, model, Olivia Culpo.

Harry Styles helped a fan propose to his girlfriend.
Bradley Chisenhall messaged the One Direction hunk, 20, and his bandmates on Twitter on Monday (30.09.14) asking them to help him pop the question to Christine Kozlowski during their gig at the Georgia Dome in Atlanta on Tuesday night (01.10.14).
The plea for help was even trending on the site with the hashtag '#1Dproposal' after he tweeted: "Help me propose to my girlfriend tomorrow night at the show."
Much to Bradley's surprise, his tweet didn't go unnoticed as mid-way through the show, Harry said to the audience: "'I have a friend in the audience who's called Bradley ... Bradley would you like to bring your girlfriend on the stage?"
The camera then panned to Bradley, who was down on one knee, as he asked his lover to marry him.
The venue was filled with shrieks of excitement and lots of clapping as Harry shouted: "She said yes!"
After the eventful evening, Bradley shared a number of photographs of him, Christine and Harry posing together, which he accompanied with the caption: Thank u @Harry_Styles for making this all happen for me& @Christinekozlo &also making my sisters @Shelbymmorgann nite (sic)."
He then added a snap shot of just himself and Harry, along with the caption: "Thanks for the help directioners!!! Y'all made this night amazing! Harry was so awesome! Thanks again! (sic)."

Mario Lopez has claimed he once had a "one-night stand with a major pop star" in Las Vegas.
The 'Extra' host has admitted he had an affair with a big-name celebrity "six or seven years ago" but is remaining tight-lipped on who they are.
Speaking on the 'Ellen DeGeneres Show' last night, the comedienne asked: "You admit you've had a one-night stand with a major pop star ... in Vegas?"
Mario replied: "Er, yes, that's correct. It was, I'm trying not to give too much away without giving too much away, it was maybe six or seven years ago? Maybe eight years ago?"
The 40-year-old hunk insists he and the unidentified star are still "friendly" but he won't reveal whether he's interviewed her since the sexual encounter out of respect of his wife Courtney Laine Mazza, with whom he has four-year-old daughter Gia and 12-month-old son Dominic, and the other mystery woman.
He explained: "My wife, who is the most important as far as her opinion to get her blessing, she's totally cool and knows everything but out of respect of her and this other person, I don't like to drop names."

Beyoncé and Jay Z have been house-hunting in Paris.
The couple, who have two-year-old daughter Blue Ivy, were spotted checking out homes near Élysée Palace in the French capital on Wednesday (01.10.14) following the end of their 'On the Run' tour last month.
However, it is not known whether the couple are looking to buy a property or rent for the short term, like they did with their Bel Air mansion earlier this year.
The pair, who have been rocked by a number of break-up rumours, rented the property in Los Angeles for a staggering $200,000 for less than a month following the end of their respective solo tours in the Spring.
Meanwhile, the duo, who got married in 2008, have also been trying to fit in some sight-seeing before their careers force them to return to the US.
The 33-year-old beauty has been keeping fans updated with their schedule by posting pictures from their excursions, including a trip to the Eiffel Tower.
Yesterday (02.10.14), the singer paid a visit to the Musée du quai Branly, which features the art and cultures of Africa, Asia, Oceania, and the Americas.
Earlier this week, Jay Z - whose real name is Shawn Carter - and Beyoncé enjoyed a child-free night as they watched the Champions League match between Paris Saint-Germain F.C. and Barcelona.

Khloé Kardashian has reportedly given her estranged husband Lamar Odom an ultimatum.
The 31-year-old reality TV star, who split from the basketball hunk last year following allegations he cheated on her and took drugs, wants her former spouse to prove he's a changed man before she'll even consider giving their marriage a second shot.
A source told the HollywoodLife.com: "Khloé still loves Lamar, but she's not even close to taking him back.
"He would have to prove that he's really changed. He'd have to go to rehab, which he hasn't done yet. But she does still loves him, so it's possible."
The former couple - who were married for four years - have reportedly been in touch with each other again after the brunette beauty reached out to Lamar following her recent split from rapper French Montana.
A source said previously: "After months of not talking, she's been calling Lamar.
"Ever since the split, Khloé's been super sad and really missing Lamar, so she decided to reach out. Lamar was so happy to hear from her."
Khloé's step-father Bruce Jenner has even been trying to get the couple back together by offering Lamar some advice on how to win back the stunning star.
An insider explained: "(Bruce) only tells Lamar to follow his heart. Bruce is old school, and tells Lamar that if he follows his heart and if his heart only beats for Khloé, go after her and don't stop!"

Mike 'The Situation' Sorrentino's tax fraud arraignment has been delayed until October 23.
The former 'Jersey Shore' star - who pleaded not guilty on two counts of filing false returns and one count of conspiracy - asked the judge in New Jersey to put his federal case on hold for two weeks as it would clash with his filming commitments on the reality TV show.
In a letter from his lawyer - obtained by gossip website TMZ.com - the star claims he and his fiancée had already signed a contract to film the programme in Los Angeles from October 5 until October 19.
The production company were concerned that Mike would be force to pull out of filming, which would mean they'd have to re-cast or delay shooting the scenes.
Mike was originally scheduled to be arraigned alongside his brother Marc Sorrentino on October 6 after the siblings allegedly conspired to fail to pay federal income tax owed on income earned for "promotional activities" between 2010 and 2012.
Mike has also been accused of failing to file a tax return in 2011 after earning $1.99 million that year.
However, Mike reportedly allowed his brother to take control of all his business dealings but, while he doesn't want to be convicted for a wrongdoing he doesn't feel he has committed, he doesn't want to make his brother - who has pleaded not guilty to conspiracy to commit tax fraud - a scapegoat.

Kristen Bell's husband Dax Shepard has to help her put her shoes on because of her growing baby bump.
The 34-year-old actress, who is expecting her second child, admits her bulging belly has stopped her from being able to reach her feet to put her footwear on.
Taking to her Twitter account last night (01.10.14) as she was travelling to the premiere of Dax's new movie 'The Judge' in Los Angeles, she said: "The bad news: u can no longer reach your feet. The good news: u have a nice hubby who'll help put on your shoes. (sic)."
The couple - who also have 18-month-old daughter Lincoln together - have struggled to think of a name for their upcoming arrival, but admit they recently had a "bit of a breakthrough" and have settled on a moniker.
Speaking to PEOPLE, Kristen said: "We've settled on one [a name], thankfully. It's a lot of pressure, especially because we felt 'Lincoln' was so perfect."
Meanwhile, Dax, 39, recently got a bell tattooed onto his left finger, instead of a wedding band, to represent his beautiful wife and had the whole family's initials placed in the centre of the little black inking.
However, it seems the hunk won't have any issues going back to the parlour to add his unborn baby's initial into the bell as he insists the tattoo didn't hurt.
Speaking about his new inking, he explained: "Actually, this was so pain free that it was actually relaxing to the point where I said to my guy, 'Do people regularly fall asleep when you do this?' And he said, 'Yeah, pretty often.' I felt myself drifting off."

Nick Jonas has a "man crush" on Daniel Craig.
The 22-year-old singer admits he admires the 46-year-old hunk - who plays fictional British secret agent James Bond 007 - and has nothing but praise for him.
When asked who his favourite male actor is, he told E News: "Daniel Craig! That's my man crush for sure. Daniel Craig. He's James Bond. He's the best.
"I'm a huge James Bond fan. I think he's a badass and I think he killed it in all his movies. Me and all my buddies, he's our guy."
Nick isn't the only one to have an obsession with Daniel as Karen Gillan admitted last month she wants to become a Bond baddie and lick the star's face.
She said: "I just want to lick [Daniel Craig's] face."
The 26-year-old actress - who plays Nebula in 'Guardians of the Galaxy' - has even come up with a plan to help her get closer to Daniel as she believes becoming a villain allows her to become a "face licker."
She added: "In the movie ['Guardians of the Galaxy'] I play Nebula, the female villain. She's really sadistic.
"One time, I had a man in a headlock, and then I just decided that Nebula would lick his face. I feel like she's a face licker."

Charlie Sheen has claimed a "bad reaction" to laughing gas caused an altercation with his dentist last week.
The 'Anger Management' star is under investigation after he allegedly threatened his dentist with a knife while undergoing surgery on an abscess, but he has denied any weapons were involved in the incident.
Charlie's representative, Jeff Ballard, told the MailOnline: "Charlie went to the dentist and had a bad reaction to the nitrous oxide which the dentist administered to him. There was no knife involved and there were no illegal drugs involved as well."
The former 'Two and a Half Men' star reportedly went "insane" and was flailing his arms when a technician placed a mask over his face to administer nitrous oxide, so she left the room and his bodyguard entered.
Following a "lot of commotion", Charlie's dentist - who had also been in the room along with an oral surgeon - left the room and told the technician his famous patient had gone after him with a knife, but he was unhurt.
The technician also reported to officers that Charlie's bodyguard had told the dentist the 49-year-old star was "high on rock cocaine" at the time of the altercation.
Charlie could face charges of possible battery against the technician and felony assault with a deadly weapon for the alleged knife attack on the dentist.
However, police are keen to interview the actor and the dentist before sending the case to the district attorney's office, who will decide whether or not to prosecute.

Selena Gomez doesn't think she handles fame "well."
The 22-year-old singer - who shot into the limelight at the age of 14 on 'Wizards of Waverly Place' - believes the past 12 months have been a vital growing period for her after she spent three weeks in rehab in January and bought her own property earlier this year.
Speaking to Into the Gloss, she said: "It's been such a transitional year for me - I moved out of my parents' house this year and into my own place.
"Sometimes, I'll be honest, I don't handle all of this as well as people think, so it's been important to really figure out what makes me feel grounded."
However, the 'Spring Breakers' star insists she's really grateful for the opportunities she's been given, even though she didn't realise it when she was younger.
She added: "The older I get, the prouder I am to be a woman in this industry."
She added: "When I was younger and running around all the time on tour, I don't think I took the time to notice how being a woman in my position is really a gift.
"I want to make sure I utilise all that power...All the stuff that I've been living [has] been beautiful and awkward and authentic."
