Miley Cyrus has managed to spark pregnancy rumours by showing off her 'food baby' on social media as she prepared for Thanksgiving and 25th birthday celebrations. A lot of her followers are not buying the idea that that's just vegan turkey in her belly, however.

Thanksgiving happened to land on the same day as the singer's birthday, and it's safe to say she is feeling the effects of this double celebration. She posted a shot of herself on Instagram posing in a long t-shirt, cradling her stomach in her hands against a backdrop featuring huge MILEY balloons. 

'So close to b-day time!' She wrote in the caption. 'Stoked for a day full of Tofurkey and loved ones! Ain't it ironic? #VeganTurkeyBaby.'

Plenty of people had something to say about the day's vegan options, but more people were interested in the sheer size of her bloated stomach. Given how small her frame usually is, it was a stark contrast to some of her older Instagram images.

On the other hand, other recent Instagram shots have not shown signs of pregnancy, so maybe fans really will have to accept that she just ate a lot of Tofurkey. Of course, they could have been older shots; indeed, there was no way of telling what was under her giant fuschia dress when she appeared on 'The Voice' recently.

There's also no reason why she couldn't be pregnant. She's been reconciled with her fiance Liam Hemsworth for well over a year now, and there have been all kinds of rumours recently that they have gotten secretly married (something that is still yet to be confirmed).

One early birthday gift that Miley DID reveal, however, was a gorgeous necklace from Liam with the name 'LiLi' spelled out with rainbow jewels. It's apparently Miley's pet name for him. 'My mannnnnn's already winnin' and it ain't even my bday yet!' She wrote on Instagram. 'Rainbow LiLi is soooo frigggggen cute!'
