Zac Efron thinks Halston Sage is a "sweetheart".
The 26-year-old actor has played coy about his relationship status after being romantically linked to the 20-year-old actress earlier this month, but he admits her caring personality has tugged at his heartstrings.
When asked about the blonde beauty, he told Access Hollywood: "She's really sweet. She's a sweetheart."
The hunky star, who has previously dated Vanessa Hudgens and Lily Collins, is thought to have got close to Halston while they were filming 'Bad Neighbours' last year.
The stars were spotted looking cosy as they took in a Los Angeles Lakers basketball game earlier this month.
However, Zac claims he's unsure if the pair are actually dating but insists he's not looking to romance anyone else.
Quizzed if he's off the market now, Zac quipped: "I don't know, I'm not really sure I'm in the market ... I'm not investing. My money's out!"
Meanwhile, the heartthrob, who sought treatment for cocaine addiction twice last year, recently admitted he's in a "great place" after conquering his demons in rehab.
He said earlier this year: "I'm so happy. I feel like I'm in a great place and I'm glad that I'm really here to share this moment with everybody and be present for all of it.
"It was an interesting year. I learned so many things. So much. The best part of it was being able to reflect upon that experience and realise how much I have learned about myself and the kind of man I want to be."

Chelsea Handler prefers to have casual sex.
The 39-year-old host isn't interested in finding a long-term partner, but she still wants to get frisky beneath the covers without having to romantically date anyone.
Speaking on 'Conan' last night (28.04.14), she said: "I have a hard time meeting men, or dating men, long-term in LA -- or in this country, for that matter -- because people can hear what I'm saying, and guys don't think it's that hot."
The blonde comedienne admitted she recently tried to hook up with a hotel manager, but things came to an abrupt end after she asked him for sex before the first date.
She explained: "I didn't want to date him, but I wanted to have some casual sex without any strings attached. That, I think, is a present to the world, you know? I think, wow, look at this, I don't want anything, I have a house, I have money, I have food."
Chelsea also admits she's not very good at flirting with men because she likes to get straight to the point and get them into the bedroom quickly.
She added: "I like to get down to business. I mean, why wouldn't I? I don't have kids, I don't want to be married. I mean can't everybody just have sex with me?"

Rita Ora claims she's never dated Nick Jonas.
The 'RIP' hitmaker has shot down rumours she's been in a relationship with the 21-year-old singer after he name-dropped her in his band's song 'What Do I Mean To You'.
Speaking on 'Watch What Happens Live!' last night, Rita explained: "I never dated him. I actually met Nick through a friend and it was a very weird situation because we were close, but it never went to that level and then I read the lyric and I kind of messaged him and was like, 'I have no idea where this came from. If you want to talk about it, call me'.
Although, despite insisting they never became an item, the 23-year-old star admits the hunk did have a crush on her.
She explained: "He was like, 'You know what, I just obviously didn't put out how I felt across to you properly'. And it was one of those situations.
"He never really told me that I think, but regardless we're still friends and I still have a lot of respect for him."
Meanwhile, Rita is currently in a relationship with Scottish DJ Calvin Harris and is looking forward to going on holiday with him after she's wrapped up 'Fifty Shades of Grey'.
She said previously: "I think [he's] ready for us to go away together, I haven't been away with him in a long time. I want to take my weave out, so it will be nice to spend some quality time."

Britain's Prince Harry has reportedly split from Cressida Bonas.
The 29-year-old royal has called time on his relationship with the 24-year-old socialite after almost two years of dating because he found her too "needy".
A source close to the prince told PEOPLE.com: "He found her too needy and it just wasn't working out."
The pair began romancing after being introduced through the flame-haired hunk's cousin Princess Eugenie - the daughter of Prince Andrew and Sarah Ferguson - in 2012.
Things seemed to be going well for the duo as Cressida attended her first official royal event last month at the launch of WE day at the Wembley Arena in London.
The couple, who were keen to keep their relationship out of the public eye, also recently sparked speculation of a possible marriage proposal in the not so distant future.
However, the blonde beauty had reportedly told her friends she wasn't keen on getting engaged just yet as she is enjoying her new job in theatre marketing.
A source said previously: "Cressida is very busy and has lots to do. Marriage is not something she's considering yet.
"She has just started a new job where she's being paid the usual salary for someone of her age - i.e. peanuts - and she has found a flat to rent with her friend Daisy.
"She is doing all the things that people in their 20s should be doing. Who knows what might have changed by this time next year but that is how she wants it to be."

Naya Rivera has reportedly been fired from 'Glee'.
The 27-year-old actress has reportedly been given the boot from the show after a blazing row with FOX's producers over her co-star Lea Michele's "diva antics" earlier this month, according to the New York Daily News newspaper.
Not only has the brunette beauty been axed from the musical show, it is also believed she's been "written out" of programme's fifth season finale, PopWrapped reports.
Naya's future on the show was questioned when she reportedly stormed off set on April 15 after the 'Cannonball' singer, whose boyfriend and on-screen love interest Cory Monteith tragically passed away last year, reportedly made the rest of the cast wait to shoot a scene as she dealt with personal matters.
However, it is believed the stars have been "icy" towards each other for a while.
An insider told Us Magazine at the time: "Naya is jealous that Lea is the show's main star. There is a lot of sighing and eye-rolling between them. They talk behind each other's backs a lot."
Meanwhile, Naya, who plays sexy lesbian Santana on the hit show, has had a rough month after her fiancé Big Sean called off their engagement and ended their relationship.
She later claimed the rapper had stolen an expensive Rolex watch from her home in Los Angeles because he is jealous of her success.
In a tweet which has now been removed, she wrote: "@BigSean stealing rolexes from a lady's house now. Maybe cuz I'm on Glee and making more money or something. #triflin' (sic)".

George Clooney has resigned from his United Nations peacekeeping role.
The 52-year-old actor, who recently got engaged to British human rights lawyer Amal Alamuddin, has stepped down as "messenger of the peace" because he's too busy.
A United Nations spokesperson, Stephane Dujarric, said: "After six years in this role, Mr Clooney feels it is time to retire his official role as messenger of peace.
"The competing demands on their time from their professional and advocacy lives sometimes make it difficult for high-profile individuals to carry out a formal United Nations role."
The hunk was given the title in 2008 following his work to raise awareness about the violence in Darfur, Sudan, and during his six years in the role he was able to travel to the Democratic Republic of Congo and South Sudan.
In March 2012, George was arrested, but shortly released, in a protest over the crisis in Sudan, and he also got the chance to meet with President Barack Obama to discuss his concerns about the country.
The news comes after George's parents Nick and Nina confirmed yesterday (28.04.14) that he had popped the question to Amal, 36, and they are "thrilled" that he is to tie the knot with a "wonderful young woman".
George was previously married to actress Talia Balsam from 1989 until 1993 and has had a number of high-profile relationships since.

Seth Rogen thought Zac Efron was a "little f**ker" when he first met him.
The 'Bad Neighbours' star admits he wasn't impressed by his co-star when he first bumped into him eight years ago, but he's since changed his mind after working with him on the new upcoming comedy film.
Speaking to PEOPLE.com, he said: "I was expecting to not like him very much when I first met him. The first time I met him I assumed he'd be a little f**ker, but that was eight years ago. I was proven very wrong because he's a sweet, nice guy ... He was just so nice, cool and very self-aware and self-effacing and endearing, and all those things that make someone hard to hate."
However, Zac - who shot to fame after landing the leading role in Disney's 'High School Musical' in 2006 - was determined to make a good impression on Seth, 32, because he saw him as an inspiration.
Zac, 26, explained: "I really made some extra effort, and after a while I think I wore him down a bit. I've respected Seth since the first movie that I saw him in. He rebranded comedy, and I identified with it, every single part of it: mind, body and spirit. That's how I want to be."

Ellen Page used to feel "awkward around gay people".
The 27-year-old star, who announced she is gay in February, revealed her sexuality to her parents when she was just 19 but she admits it took her longer to come out in public because she felt ashamed of who she was.
Speaking in the June issue of Flare magazine, she said: "You think you're in a place where you're all, 'I'm thrilled to be gay, I have no issues about being gay anymore, I don't feel shame about being gay,' but you actually do.
"You're just not fully aware of it. I think I still felt scared about people knowing. I felt awkward around gay people; I felt guilty for not being myself."
However, the 'Juno' star felt the need to come out as she got older because she wanted to be able to show her girlfriend off to the world without anyone judging her.
She explained: "The more time went by, the more something just happened, and, Oh my god -- I want to love someone freely and walk down the street and hold my girlfriend's hand."
The brunette beauty admits her revelation has since lifted a great weight off her shoulders and she feels confident and content within herself.
She added: "I felt happy and confident and the difference was huge ... I feel more creatively inspired than I have in years. And I'm sure it has to do with a lot of bricks being taken out of the backpack."

David Arquette has become a father again.
The 42-year-old actor and his girlfriend Christina McLarty welcomed their baby son Charlie West into the world on Monday (28.04.14) at 12:35pm in Los Angeles.
The tiny tot weighed a healthy 8lbs 7oz and is said to be doing "well" following his birth.
David's representative told PEOPLE.com: "Mum, dad and baby are doing well.
"They appreciate all of your well wishes and thank you for respecting their privacy at this time."
David, who also has nine-year-old daughter Coco with his ex-wife Courteney Cox, recently admitted that he was keen to give his son a "traditional" name.
He said previously: "I think we will go with something a little more traditional. I've been a bit cryptic about it. It's going to be the name of my grandfather used to play."
Meanwhile, the hunky star is looking forward to seeing Christina, whom he has been dating on/off since 2011, adapt to motherhood and watching the tot growing up.
He said earlier this year: "It's all new, but it's all beautiful. Playing catch, making [his son] laugh, and seeing my girlfriend Christina being a mother for the first time and all the joy and love that it's going to bring her and me."

Cameron Diaz has had a romantic relationship with a woman.
The 'Other Woman' star - who stars opposite Leslie Mann and Kate Upton in the comedy - previously admitted she finds women "beautiful" and has now confessed she has had sexual relations with a female in the past.
Talking on Bravo's 'Watch What Happens Live' during the 'Plead the Fifth' segment with Andy Cohen, who asked if she'd ever "swam in the lady pond", she admitted: "Yes, I have been with a lady, yeah."
Cameron previously dated pro baseball player Alexander Rodriguez for a year before they split in 2010 and, talking about the highlight and downsides of their relationship, she joked: "I think schedule, and schedule."
Meanwhile, her co-star Leslie recently confessed she wishes she could experience sex from a male perspective and see how the "real mechanics" feel for them when they get frisky beneath the sheets.
Asked what she would do if she became a man for the day, she replied: "I would have sex. I would love to know how it operates! Like what the real mechanics feel like! It would be fun to feel the other side, wouldn't it?"

Sir Paul McCartney played his first ever show in Ecuador last night (28.04.14).
The former Beatles star took to the stage at the Estadio De Liga in Quito, 2,800 metres above sea level, making it the highest concert Paul has ever played.
To celebrate his visit, local authorities organised for a meet and greet between the musician and the Ecuadorian Beatles Fan Club, who created an impressive giant logo for his latest album 'New' on the Pichincha Mountain, an Ecuadorian landmark, which could be seen across the entire city.
The 71-year-old star performed for almost three hours and also gave a special rendition of the Beatle's hit 'All You Need Is Love' on the piano, which is being used in a global tourism advert for Ecuador.
He later took to Twitter and posted a photograph of himself carrying the flag of Ecuador on stage, along with the message: "Ecuador - what a night! Thank you. (sic)"
Paul, who released his record 'New' last year, is currently on the South American leg of his 'Out There' tour and has also performed in Uruguay, Chile and Peru, while later this week he will also take to the stage in Costa Rica for the first time.

Kim Kardashian and Kanye West are allegedly getting married this week.
The reality star and her rapper fiancé were rumoured to be having a lavish wedding extravaganza in Paris next month in front of all their family, friends and celebrity acquaintances, but TMZ are now reporting the couple are going to break with expectations by holding a highly secretive ceremony in the next few days.
Sources told the gossip site the couple already have a marriage license and intend to get hitched before the week is out.
Kim, 33, and Kanye, 36 - who have 10-month-old daughter North West together - are so intent on keeping their nuptials private that they have secured a "confidential" marriage license so no one officially knows.
However, the lovebirds want to make up for their minimalist big day with an extravagant bash in the days following the event.
This marks a big turnaround for 'Keeping Up With The Kardashians' star Kim, who wed basketball player Kris Humphries live on TV in August 2011 following a 90-day engagement.
The star-studded affair took place in Montecito, California, and was filmed for a two-part, four-hour TV special on E! called 'Kim's Fairytale Wedding: A Kardashian Event'.
The couple called it quits after just 72 days of marriage, with Kim citing "irreconcilable differences".
