Demi Lovato has injured her arm.
The 22-year-old singer worried fans last night (19.09.14) after she posted a picture of her wrist in a sling on Instagram, just hours before her 'Demi Lovato: World Tour' gig in San Antonio, Texas.
Alongside the snap, she wrote: "Welp. Looks like I won't be playing guitar, piano OR drums tonight. San Antonio... Why did you have to go and make me fall so hard for you?!! #demiworldtour (sic)."
This isn't the only injury the brunette beauty has sustained this summer as she also sprained her ankle in July after going for a quick run.
She tweeted, alongside a picture of her swollen ankle, at the time: "Umm soooo... I guess when I went running and twisted my ankle I actually did hurt myself... AGAIN. Hahaha (sic)."
Meanwhile, Demi, who sought treatment in rehab for eating disorders, drug abuse and a self-harming disorder in late 2010, has hired activist Spencer West to share "his empowering message" before she takes to the stage every night in favour of a warm-up act.
Announcing the news on her Facebook page yesterday, she said: "Spencer West is not only a really great friend of mine, but a huge inspirational speaker. After I spent some time around him and realised what an amazing person he is and how incredible he is at speaking, I decided to bring him on tour."

Paloma Faith lied about her age to get a record deal.
The 'Picking Up the Pieces' hitmaker told bosses she was 23 when she was actually 27 at the time because she thought she was too old to get signed.
Speaking to the Daily Mirror newspaper, she said: "When I was asked what my age was in that first meeting, I blurted out 23, when I was actually 27.
"I didn't plan on doing it beforehand and it wasn't a calculated thing. It was only afterwards I realised why I said it ... I felt that everyone was going to focus on my age, not my music ... I think if I'd said I was 27, I wouldn't have got signed. One hundred per cent."
She added: "Of course now everyone is like, 'Oh we didn't mind' but I think if I'd come out and been honest in the first place, they'd have been like, 'Oh, she's a bit old and she's making all these mistakes.' "
She added: "I don't regret it and think I did it for the right reasons. I think we live in this era where men in particular are afraid of baby-making age and until you've established yourself, you're not forgiven for it."
The 33-year-old beauty also jumped to Madonna's defence and hit out at people who criticise the 56-year-old singer's revealing outfits and sexy dance moves.
She explained: "People talk about Madonna, saying she should stop wearing all that stuff, she's too old for that kind of thing now. But why? She's been doing it all along. She's entitled to wear that but at the same time, it was important for her to do that, back in the day."

Natalie Imbruglia wants to buy a house in Australia.
The 39-year-old singer, who was born in Sydney, has been living in London for 20 years but she's now considering moving back to her native home next year and buying a property with a vegetable patch.
Speaking to Australia's Daily Telegraph, she said: "It's time for a veggie garden! I've never had my own place here, so it's a new beginning."
However, the brunette beauty still manages to experience some home comforts when she's in the UK as she gets her mother to send her calorific treats, which are only available in Australia.
She explained: "Mum still sends me Tim Tams and Twisties, though..."
Meanwhile, Natalie - who shot to fame after starring in soap opera 'Neighbours' in the '90s - recently admitted that she's considering joining dating app Tinder, which lets users judge each other based on appearance, in the hope of finding love and believes it's a great way to get to know someone before you meet them in person.
She said: "That's how all my friends in London are meeting people. Why not? You can establish where someone is at before you meet them through texting and discussion."

Jessie Ware would "love to have a baby."
The 28-year-old singer can't wait to start a family with her husband Sam Burrows but admits her forthcoming new album 'Tough Love' and subsequent tour have put their baby plans on hold for the time being.
When asked if she would like to have children, she said: "We're just working out the best time to pop one [a baby] out!"
The couple, who first met when they both attended a co-educational independent school in Dulwich, tied the knot on the Greek Island of Skopelos, where they also got engaged, a few weeks ago and the brunette beauty still hasn't got the hang of calling Sam her husband.
When asked how life has changed since getting married, she told the MailOnline: "[It] doesn't feel too different. It feels so funny calling him my husband."
Meanwhile, the tracks featured on 'Tough Love' are based on Jessie's past experiences on romance, but she insists not all of the songs are based on Sam.
She explained: "A lot of the songs are fantasy and embellished thoughts where I'm telling a story.
"I absolutely think that if I wrote a full album about our relationship it would be so dull because we don't fight and are easy going!"
'Tough Love' is set for release on October 6.

Keyshia Cole was arrested on suspicion of battery yesterday morning (19.09.14).
The 32-year-old singer was detained by police in Los Angeles after she allegedly attacked a woman at the house of her rumoured boyfriend Birdman around 5am.
A source told TMZ.com: "For some reason security let her go up to Birdman's penthouse and when she got in she saw another woman and went nuts. Keyshia attacked her ... leaving scratches all over her face."
The songwriter, who has four-year-old son Daniel Jr. with her ex-husband Daniel Gibson, was also arrested for an outstanding reckless driving warrant.
Keyshia was reportedly taken to the Valley Jail in Van Nuys in California and spent seven hours behind bars before being released later that day on $46,000 bail - $20,000 for the battery charge and $20,000 for the driving offence - according to the MailOnline.
Following her release, the brunette beauty took to her Instagram account to post a series of cryptic messages, which led her fans to believe she'd split from Birdman, whose real name Bryan Williams.
She posted a picture of a quote, which read: "My Real & Your Real Ain't The Same That's Why We Don't Click (sic)" alongside the caption, 'Fake. Just a fake.'

Justin Bieber has promised to shave his moustache.
The 20-year-old singer posted a picture of his facial hair on his Twitter account last night (19.09.14) but before his fans had the chance to criticise his new look, he insisted it wouldn't be sticking around for very long.
Alongside the snap, which sees him gazing into the camera lens with his face resting on his clenched fist, he wrote: "I'll shave it calm down (sic)."
This isn't the first time the 'Baby' hitmaker has attempted to grow a moustache as he also flaunted his barely-there fluffy facial hair at the end of last month.
However, after he was bombarded with negative comments on social media, he shaved it off on camera and posted the clip on his Instagram account.
The Canadian hunk, whose appearance has changed dramatically since he first arrived on the pop scene in 2008, can be heard asking a friend in the short video, "Should I do it?" and "RIP 'stache!"
He begins the clip by applying shaving cream to his face and asking his friend, "Is this how you do it?," who responds by saying, "I think that's how you do it."
The pop star then says: "Here I go!" as he takes his battery-powered razor and begins to remove the hair.
Meanwhile, Justin has recently rekindled his romance with on/off girlfriend Selena Gomez, whom he first started dating in 2010, and has even reportedly asked her to move into his Los Angeles apartment with him.

Chrissy Teigen "can't wait" to see John Legend use Viagra when he gets older.
The 28-year-old model is looking forward to growing old with the 'All of Me' hitmaker, whom she married last year following 10 years of dating, and is even thinking about how they might require the help of the erectile dysfunction treatment to boost their sex life.
Speaking to Us Weekly magazine about how her life has changed since tying the knot, she said: "I think you are just more comfortable talking about the future more. I was the kind of girl that never talked about marriage and kids ... [Now] you just end up talking about everything as forever which is very cool.
"It's nice to be able to be like, 'I can't wait to see you with grey hair, it's going to be hysterical.' Or, 'I can't wait until you have to use Viagra.' "
Meanwhile, the brunette beauty is planning to have "a lot" of children with the 35-year-old singer but admits their conflicting work schedules make it impossible for them to start trying for a baby at the moment.
She explained: "I want a huge family. We want a lot of kids. When it happens, it happens. For us it's hard because he's on the road so much and I'm working.
"People think it happens so easily ... but the stars really have to align to have a baby and it is a little miracle so when it happens ... we will be so happy."

John Cusack thinks being a child star is "brutal".
The 'High Fidelity' actor - who appeared in his first film 'Class' aged 16 - believes finding fame at a young age can be a "damaging" experience and feels he's had a lucky escape.
When asked how he felt about the treatment of child stars, he told Shortlist magazine: "Yeah, its brutal. I got into films [at the age] where it can do a lot of damage - 16. I started with people who got damaged.
"But it's different now. It's much worse than it was. Back then, there was an expectation of private life. There were areas you could go and make mistakes [without public attention] because what else were you going to do between the ages of 16 and 25 but make mistakes."
The 48-year-old actor's latest film 'Maps To The Stars' is due out next week and has been described as an extension of "obscene and crazy" Hollywood life, although he insists the movie is "tame" in comparison to the difficulties facing young stars.
He explained to Shortlist magazine: "Here we are in Toronto at the Toronto International Film Festival, and there's a TV channel doing live 'breaking news' coverage that is tracking - in real time - Justin Bieber's movements into a mall. This movie is tame in comparison."

Thom Evans is dating his 'Strictly Come Dancing' partner.
The former professional rugby player - who has previously dated Kelly Brook and American actress Jessica Lowndes - is said to be "completely smitten" with dancer Iveta Lukosiute.
A source told The Sun newspaper: "He is completely smitten. We didn't think Iveta would be his type but he had a huge crush on her from the get-go.

An insider told The Sun newspaper: "The cast were falling about themselves with excitement and lining up to have their photos taken with George.
"The girls were mad keen to speak to him. He was full of jokes and had them all in stitches.
"'Downton' is now a global phenomenon and they are used to red carpet events with Hollywood A-listers. But this was George acting alongside them."
Laura Carmichael - who plays Lady Edith Crawley on the hugely popular ITV show - admitted George's appearance on the show was such a secret that the cast "didn't know if it would actually happen" until he arrived on set.
She said: "It was amazing. We didn't know if it would actually happen until he turned up.
"We were filming and then heard, 'He's here! He's here! He's arrived!' "
Meanwhile, it was recently revealed reality TV star Kim Kardashian West is also keen on a role.
She admitted: "I'm a big fan. I'd love to be on it if they asked. I love things like that."

She told the Daily Mirror newspaper's We Love TV magazine: "This is a whole different thing for me.
"My outfit is quite low-cut. I hope there are no 'nip slips.' "
The 'Mama Do' hitmaker is managing to strike a balance between her music career and 'Strictly' commitments, and she has had her professional dance partner Trent Whiddon training her in spare time between live concerts.
She recently said: "At the moment, I'm performing around the country so Trent is travelling with me so we can fit in some training.
"I'm dreading serious dances such as the tango. I'm looking forward to fun dances like the salsa."
She has also dismissed rumours of a rivalry between the female stars on this year's show.
She previously insisted: "Me and the other Strictly celeb girls have set up our own WhatsApp chat group and we send each other selfies of us in training, as well as just having a gossip.
"It's been really nice."

"It's really hard, but I've always liked the clash of things. You get to be in one world, and the next minute you're in another world."
The blonde beauty admits she was forced to take a break when she got pregnant for the third time.
She said: "It was really hard for me to do much else, so I kind of had to walk away."

She told People magazine: "It reflects where I am right now, everything kind of aligned.
"I really enjoy the process of making the clothes, almost as much as I do wearing them."
