Did Beyonce doctor her birthday bikini pics? That's what fans with a keen eye want to know!

Earlier this month, Beyonce posted some sexy photos of herself from her 33rd birthday aboard a yacht in the Mediterranean. And while the Queen B was looking mighty good in her snakeskin bikini, fans have been accusing the sultry singer of photoshopping the snaps to make her thighs look slimmer.

A celebrity photoshopping images to appear more attractive or skinnier than they are?! NEVER!

At first we just thought this was fans crying wolf, but on further inspection, the stair between her upper thighs does tilt up in a diagonal angle -- which is just not what stairs do. The evidently altered stair all but confirms to us that the svelte stunner touched up the pic before posting it on her Tumblr page.

We have to say -- we're a little surprised that Beyonce would go through that much trouble for a social media snap ... which leads us to wonder what other lengths she would go to for her image ...? Cough cough ... pregnancy No. 2 rumors ...

In other Bey and Jay news, the couple reportedly took a dramatic "U-turn" in an special commitment ceremony during the vacay. Reportedly the couple renewed their vows in Corsica during the bday trip.

According to Grazia magazine, Beyonce decided the milestone was the perfect point to put all the negativity behind them and move forward as a couple.

A source tells the magazine: "They were joined on a private beach by Beyoncé's mum Tina, their daughter Blue Ivy and a small group of close friends and recited a new set of vows during a short but very romantic ceremony, which doubled up as a birthday celebration."

The source added that it was quite the luxurious affair: "The small wedding party celebrated with drinks and food made by the couple's private chef. Afterwards, they rented a luxury $500,000 a yacht to cruise around Italy, which they have been calling their second honeymoon."
