Why is everyone talking about Taylor Swift's bum? Experts have their say

TAYLOR Swift shocked everyone recently when she stepped out with a much bigger behind.
The Bad Blood singer – who was attending the iHeartRadio Awards – wore a black sequin jumpsuit that left fans questioning whether or not she had had butt implants.

Taking to social media 1 fan wrote: "Fake butt alert! So @taylorswift13 went from flat pancake a*s to normal sized booty overnight? I'm DONE".
However, others gave the award-winning solo artist a bit more credit, insisting that she'd just been working harder in the gym.
"She's been doing some squats," 1 fan simply argued.
So we spoke to the experts to find out what Calvin Harris' girlfriend could have done to get her derrière in tip top shape.

1. Cosmetic surgery
Aesthetic medicine body specialist, Vanessa Bird, believes that the 26 year old's new look is a result of body contouring rather than surgical treatment.
Speaking exclusively to OK! Online, she said: "Taylor certainly looks to have undergone some sort of body contouring treatment such as BTL Vanquish ME; her buttocks look firmer, fuller and lifted.
"This could maybe be a result of surgery, but we know Taylor is a fan of dancing and exercise and is more likely to have sought out a non surgical treatment to lift her bum, and/or enhance the results of a a good fitness routine.

"BTL Vanquish ME and Exilis Elite are excellent options for women looking to reshape their bottom, reduce fat and contour the lower body.
"They use radiofrequency energy to reshape the body, rather than surgery, making them popular with celebs who need results with zero downtime."

2. Butt implants
Laura Casewell, Editor of The Harley Street Journal, reveals that the star could have had plastic surgery.
She told OK! Online exclusively: "Taylor's bottom looks lifted and rounder, which could be the result of non surgical body contouring treatment, fat transfer, or butt implants.
"Implants are usually placed under the muscle during a surgical procedure which can take around 1-2 hours. It's unlikely she's had fat transfer in my opinion as she's very slim all over, making energy-assisted bum lifting or butt implants more likely."

3. Exercise
Or it's quite likely that the beautiful blonde just worked ridiculously hard at the gym. We spoke to personal trainer, Anthony Murray, at Fitness First to find out how to get the look. Here's what he exclusively suggested:
Sandbell Curtsey Lunge
Stand with your feet together and hug a heavy Sandbell close to your chest. Engage your core and make sure your torso is kept upright.
Step your left leg behind and across you, ensuring your knee is lowered into a curtsey position. Return to the standing position, pause to regain your balance and then repeat the move on your right leg.
Repeat 10-15 times on each side. Do 3 sets with 30 secs rest in between each set.

Squats
Stand with your legs apart, slightly wider than your hips and with your toes pointing outwards.
Hold a Kettlebell close to your chest and keep it close to your torso to protect your spine. Engage your core and bend into your knees whilst squeezing your glutes at the same time.
Make sure your back is straight whilst you perform the downward move and return to the top.
Repeat 12-15 times. Do 3 sets with 30 secs rest in between each set.

Single-Leg Hip Bridges
Lie flat on your back with your left leg bent and the sole of your foot flat on the ground – this will be the leg you’ll be working.
Raise your right leg straight in the air and then push through the sole of your foot and raise your hips as high as you can.
Pause for 1-2 seconds at the top and then slowly bring your hip back down to the ground. Make sure you’re engage your core and glutes throughout. Repeat the move with your other leg.
Repeat 20-24 times. Do 2 sets with 30 seconds between each set.

4. Butt pads
The other option is that Taylor has gone all Amber Rose on us and has begun wearing butt pads.
Remember when Wiz Khalifa's ex wife stepped out with her's firmly on show last year?
