Ashton Kutcher thinks one-night stands are "gross".
The 'Two and a Half Men' star - who is believed to have recently got engaged to his former 'That 70s Show' co-star Mila Kunis - thinks it can be "fun" not to be attached to anyone, but eventually single life gets tiring.
He told Men's Fitness magazine: "Being a single guy can be a lot of fun ... when you're financially independent [and] can do whatever you want, whenever you want....
"For every girl you have a good time with for one night, if you want to stay single, that's the same girl that you have to not call back.
"After a while, being the one-night-stand guy is also just a little gross."
The 36-year-old actor began dating Mila after his marriage to 51-year-old 'Ghost' actress Demi Moore broke down, and his new fiancée is now set to appear in his hit sitcom 'Two and a Half Men'.
CBS announced yesterday (04.03.14) that the 30-year-old actress will play Vivian, a young, free spirited traveller, who turns up on Ashton's character, Walden's, doorstep and plays with his heart strings.

A furious Tina McIntyre will slap her lover Peter Barlow in 'Coronation Street' next week.
The Weatherfield barmaid - played by Michelle Keegan - turns violent as she realises Peter (Chris Gascoyne) has no intention of calling off his marriage with Carla (Alison King) to be with her.
A source told Inside Soap magazine: "He does love a gamble, does our Peter. He's playing a high-risk game and he thinks he can keep Tina onside. Let's hope for his sake that he can."
Peter has promised to tell Carla about his illicit affair with Tina, but she is left fuming - and heartbroken - upon discovering he still hasn't followed through on his vow.
The insider added: "How hasn't she learned what he's like? Peter is as familiar with the concept of honesty as Emily Bishop is with going out clubbing. It would appear Tina is heading for serious disappointment. She'll never get Peter to do what he doesn't want to do."
The soap love triangle will be further complicated when the less-than-maternal Carla discovers she's pregnant next week.
However, Peter's two worlds collide as Tina also falls pregnant with his baby in a sensational storyline that will lead to Michelle's exit from 'Corrie' later this year.

Pharrell Williams thinks Miley Cyrus and Daft Punk were "gracious" for agreeing to collaborate with him.
The 'Happy' hitmaker worked with the 'Wrecking Ball' singer and French duo, along with Justin Timberlake and Alicia Keys, on his new album 'G I R L', and feels blessed he managed to get so many stars to feature on the record.
He told Entertainment Tonight: "Yeah, you call them and say, 'Hey, I need you', and they were all very nice and gracious enough to do it.
"I wanted people who emoted when they do what they do, it needed to be more than just their great voice and how it sounds."
The 40-year-old star, who was nominated for an Oscar for his track 'Happy' from the film 'Despicable Me 2', knew he wanted the new record to be "visceral and urgent".
He explained: "I knew I wanted it to be celebratory and festive. It's the album I've always dreamt of making. It's a love story, and that's why the album is made for human beings, it's made for everyone. It's just that my muse were women."
The singer is pleased his fans have reacted well to the solo record and feels lucky to have had so much support.
He added: "It's pretty awesome and I have the people to thank, because they lifted me this high."

Jennifer Lawrence played a prostitute as a child in a church play.
The 'American Hustle' star learnt how to perform for audiences during a production about 'The Book of Jonah' and her mum claims she stole the show.
According to The Sun newspaper, her mother Karen said: "This little extra called Jennifer just took over. She played the best prostitute."
Lawrence, who missed out on a Best Supporting Actress Oscar to '12 Years a Slave' star Lupita Nyong'o at the ceremony on Sunday (02.03.14), is now having a year-long break from making films.
Karen continued: "Her Oscar schedule was basically in minutes and milli-minutes so it is exhausting for her.
"All these awards shows are not so glamorous for her because it's work and it's exhausting.
"I know her favourite thing to do is work then come home, eat up all the popcorn, put on her pyjamas and do nothing."
The 23-year-old star has been working non-stop appearing in 'The Hunger Games' franchise and 'X-Men' series, along with other films, and movie mogul Harvey Weinstein feels she deserves a break from the industry.
He said: "Jennifer is too nice and will do people favours and agrees to do movies like 'American Hustle' when she could have had a rest."

Simon Cowell has "thick skin" when it comes to the upcoming 'X Factor' musical 'I Can't Sing'.
The 54-year-old music mogul isn't worried about being spoofed in the new theatre show - which was written and created by Harry Hill - and didn't want to make changes to the script, even though it may not show him in the best light.
He explained to Radio Times magazine: "I have not changed a word and I wouldn't. If it feels like it's got my hands over it, people won't enjoy it as much. I've got thick enough skin."
The 'X Factor' creator admits he isn't a musical theatre fan and was reluctant to agree to the show at first, but Harry's funny script and songs won him over.
He recalled: "I thought, 'Oh Christ, what if I hate it?' So I said to my PA, 'Get me a seat at the back near the exit.' I hate musicals, but these songs were great and within five minutes I was in hysterics.
"We all get it in the neck, particularly me, but we didn't want to make something pompous or earnest."
And Simon isn't worried about 'I Can't Sing' undermining the integrity of 'The X Factor'.
He explained: "If I thought it was damaging to the brand we wouldn't have done it.
"Any show that has Wagner competing against One Direction or that can turn John and Edward into multimillionaires is a bit wacky. It's a bonkers show in a way. I mean, Louis [Walsh] on the panel? It's nuts!"

John Mayer thinks ex-girlfriend Katy Perry is "extremely driven".
The 'Who You Love' hitmaker, who split from the singer last month, has praised her work ethic and spoken about the reason women often decide to get back with their ex-boyfriends.
He told America's Sirius Radio: "It is a connection to the past, a reaction to fear of the unknown. They go back with a guy they don't like just because they know how to get to his bathroom in the dark."
The 36-year-old star, who had an on/off relationship with Katy from 2012, went on to gush about the 'Dark Horse' singer, who is in Sydney, Australia promoting her upcoming Prismatic world tour.
He said: "She's extremely driven and extremely serious about doing great work."
Katy, 29, reportedly broke up with John because he kept breaking promises and their conflicting schedules have made it difficult for them to continue their relationship.
A source said: "The last time they broke up John won her back by making a ton of promises. He was going to put her first, but now he's falling back into his old patterns.
"Like, he shuts off his phone and disappears all day and night - he says it's because he needs alone time, but it's sketchy for sure."
Katy was left heartbroken when her marriage to Russell Brand ended after 14 months in December 2011 and she "isn't willing to put up with any shenanigans" from men.
Meanwhile, John has already been spotted with a mystery brunette during a night out at the Sunset Tower in West Hollywood on Saturday (01.03.14), just days after splitting from Katy.

Katie Holmes insists her number one priority is making sure her daughter knows she's special.
The actress, who has six-year-old daughter Suri with ex-husband Tom Cruise, is a hands-on mother and claims although times have changed the basic principles of parenting remain the same.
She told the April edition of ELLE magazine: "Children are exposed to so much more than we were, I suppose every generation goes through that feeling of, 'Oh my God, it's so different from how I grew up."
She added: "I think the basics are very important: The number one thing is making sure my child feels loved. And good about herself.
"And that what she does and who she is, is special and important, and should be celebrated."
The 35-year-old star, who was married to actor Tom from 2006 until 2012, says motherhood has changed her outlook on life and she has a lot respect for women.
She said: "I think all of our experiences bring us to a greater understanding of ourselves and help us realise what is most important.
"That being said, I have three older sisters and one older brother and I went to an all-girls school, and have always been a fan of women.
"I support women and all experiences give you more insight into others, as well as yourself."
Katie grew up in Ohio with her four siblings and parents Martin and Kathleen and claims she learnt a lot from watching her older sisters growing up.
She said: "I was pretty lucky ... I'm the youngest of five with three older sisters, so when I was a little girl, I spent a lot of the time in the bathroom just watching them.
"I was intrigued by make-up and my mum was very frank with us and said, 'There are natural beauties in the world, but make-up enhances."
Her acting career began at an early age when she joined the cast of Dawson's Creek, which aired between 1998 and 2003, and she is thankful she became famous during a time when fans weren't able to use Twitter and Facebook.
She said: "The world has changed so much since then. Social media, and what people are watching. But I think innocence was one of the draws of the show.
"It was these kids going through first love and heartbreak and growing up and friendships changing. So I'm glad that the innocence still holds up."

Anthony Mackie wanted to wear spandex for 'Captain America: The Winter Soldier '.
The 35-year-old actor was thrilled to be cast in the superhero adventure as the Falcon, also known as Sam Wilson, because he thought he would be able to attract female attention when he showed off his hunky body in the skin-tight material.
He told SFX magazine: "When I got the call, and they told me I was gonna be on this movie, I was so excited because I was like 'I'm gonna get to work and wear spandex and all the women are going to be like 'Oh my god, look at his body in spandex!'' "
Mackie was devastated to learn he wouldn't be donning spandex but wears it under his costume so he can feel like a superhero.
He added: "I was like 'no spandex?' I was highly upset. I wear spandex under my costume just so I can feel like a superhero."
The 'Pain & Gain' actor will hit the big screen alongside Chris Evans, Scarlett Johansson and Samuel L. Jackson in the forthcoming film.

Monty Python's groupies were never as attractive as rock groupies.
The British comedy troupe - which is made up of John Cleese, 74, Terry Jones, 71, Terry Gilliam, 72, Michael Palin, 70, and Eric Idle, 70 - admit they had a huge fan base in at the height of their fame, however, the girls who chased them weren't as gorgeous as the females who followed their musician friends.
Gilliam - who is married to Maggie Weston - told GQ magazine: "There were groupies. But comedy groupies are not as good looking as rock groupies, that's all I can say. I mean, really interesting personalities! But the beauties we saw knocking on the doors in 'A Hard Day's Night' and all those rock shows were not the girls who were knocking on the Python stage door. Funny that!"
The comic group - who were once dubbed The Beatles of comedy - weren't only popular with the general public, they also had a number of A-List fans who loved watching their sketches, including Jimmy Page, George Harrison, Sir Paul McCartney and Robert Plant.
Gilliam revealed: "We were hot. When Python was at its peak, every group, whether it was Led Zeppelin [or] The Beatles, loved us. We were 'THE' guys!"
Monty Python have reunited for a series of live shows at The O2 in London this summer entitled 'Monty Python Live (Mostly), 'One Down Five To Go' - a reference to late member Graham Chapman, who died in 1989 at the age of 48.
Late Beatles guitarist George Harrison was such a big Monty Python fan he financed their controversial 1979 film 'The Life of Brian' through his company HandMade Films.

Dame Helen Mirren fixes things in Winona Ryder's home.
The 'Queen' actress and her husband Taylor Hackford rent a property to the 42-year-old screen beauty and the Oscar winner is always on hand to do emergency DIY if something breaks in the property.
And the 'Turks & Caicos' star admits she is a little in awe of her multi-talented and famous landlady.
Winona told Red magazine: "She and Taylor Hackford have this mansion and I rent a little cottage in the back. If I'm having a problem with the house, she'll come up and fix it.
"She is everything you would hope she'd be, wonderful, warm and funny. I had to tell her that I love 'Prime Suspect' so much that for 10 years I stayed in hotels under the name DCI Jane Tennison."
Winona also revealed she feels "liberated" now as she has finally shed herself of the "anxiety" that plagued her during her younger years.
She said: "It's so liberating when you get over that anxious feeling you constantly have when you're younger. I was about 38 when it happened.
"You watch younger friends go through it and there's nothing you can do. It's like when someone's in a bad relationship and you know there's nothing you can say that's going to make them leave but they'll get there on their own.
"I've been there. We've all been there. You're not ready until you're ready."

Sarah Harding won't take solo career advice from Girls Aloud.
The 32-year-old singer has revealed she is so strong-willed that she is unlikely to listen to musical tips from her former bandmates Cheryl Cole, Nadine Coyle, Kimberley Walsh and Nicola Roberts, who have all released solo albums in the past.
She explained to the latest issue of new! magazine: "They've all done solo work but there's nothing they can say. I don't take advice - I'm not good at listening. I just learn my own way. I've always been stubborn."
The 'Promise' hitmaker says her solo music is more mature than the pop records she performed with Girls Aloud.
She teased of her new music: "It's a bit more grown-up. I've co-written quite a bit of it and a lot of the songs reflect who I am as a person. I can connect with them."
However, Sarah admits she has butterflies about putting her own music out there as she it is so personal.
She added: "I'm really excited, but nervous too. I'll be putting my soul out there for everyone to see."

Kristin Cavallari is "counting down the days" until she gives birth.
The former 'The Hills' star and her husband Jay Cutler are expecting a baby boy - their second child together - in April, and the blonde beauty admits she can't wait to see the tiny tot for the first time.
She said: "[I'm] counting down the days."
The 27-year-old actress insists she's trying to eat the same stuff she was eating before she fell pregnant and has been doing home workouts in a bid to stay fit and healthy.
She quipped: "I feel like I have a bowling ball in my stomach."
She added: "I'm eating the same I normally do, and I'm working out but I'm not killing myself. I just don't use it as an excuse to go crazy, I guess. I've been doing videos at home and I've been doing lots of squats and lunges and really trying to focus on my legs and my butt."
However, Kristin, who also has Camden Jack, 17 months, with her NFL star husband, hasn't been able to stay away from the calorific treats, but she admits she has always had a sweet tooth.
She explained to Us Magazine: "I crave sweet things, but it's no different than when I'm not pregnant. I pretty much have dark chocolate every day because I don't think it's bad for you, and we get this coconut bliss ice cream made with coconut milk. I'll eat that a lot. It's amazing. When we go out to eat, Jay and I always get dessert. He has a sweet tooth, as well."
