Taylor Swift's convoy sneaks into back of Madison Square Garden ahead of HUGE rehearsal dinner for wedding

The Bride is in the building.

’s convoy was spotted arriving at Madison Square Garden ahead of her wedding rehearsal dinner this evening in exclusive Daily Mail pictures.

The blushing bride, 36, was seen being swept into the back of the iconic venue in a blacked-out silver Suburban with an extended roof and communications antennas.

Her arrival at 3.59pm comes less than two hours before her rehearsal dinner at the Infosys theatre, where 100 of her closest friends and family will gather to celebrate her impending nuptials to , also 36.

Guests are expected to enter in a stream of blacked-out SUVs through 4 Penn Plaza, where the Cruel Summer singer’s team have been busily erecting drive through tents to block prying eyes.

As we previously reported, the dress code for the rehearsal dinner is 'cocktail attire', a source said, with only family members and close friends expected to be in attendance at MSG's smaller Infosys Theater.

It comes ahead of Friday's wedding, where over 1000 guests are expected to attend as celebrations stretch into the early hours.

Those guests are

'Everybody's feeling good, but I think everybody's ready for it to be over,' one source candidly admitted to the Daily Mail in an exclusive interview.

According to the well-placed insider, part of the nerves stems from loved ones not wanting to slip and share too much information with the public or the press, as every little detail of the highly anticipated nuptials is under a microscope. 

'Nobody wants to be the one to divulge plans and get in trouble, so they're on edge about that,' the source added, without detailing what those repercussions may be.

We're told it's become the norm for 'everyone to go along' with what Swift wants.

The bride and groom have made serious attempts to keep their guests' lips sealed.

The Daily Mail was the first to report in April that the couple  (NDAs) along with their save-the-dates, and guests had to sign them to receive the actual wedding invitation.

Although we were told at the time that it is unlikely either Swift or Kelce, both 36, would ever take legal action against their family or friends, our first insider said guests have taken the agreement very seriously.

'The NDA was a lot and I think everyone is scared of [Swift's team],' the source said.

The Daily Mail also reported on Wednesday that Swift's longtime stylist Joseph Cassell Falconer helped create custom outfits for family members.

It appears Swift wants total control over her wedding - and what gets released. 

As the Daily Mail previously reported, there are rumblings that the nuptials 'will be recorded' for a possible wider release. A source told us in March that the Grammy winner wants to be able to share these special moments with her loyal fans.  

Aside from the NDA, we're told other extreme measures have been taken to keep everything under wraps in the days leading up to Swift walking down the aisle.

Earlier this week, another source told us that everyone who enters the reported wedding reception venue, Madison Square Garden, has their phones taken away.

Now, the Daily Mail has exclusively learned that on-site security has gone a step further by having everyone in the area wear a tracker on their wrists.

'When they give you a wristband, they take your picture and the wristbands could be tracked everywhere in the building,' the source explained of how the added security measure apparently works.

'They can see where you are; must have an RFID [radio-frequency identification] or something,' they added.

As of now, it is unclear whether Swift and Kelce's celebrity guests and relatives will also be required to don the tracker on their wedding day, but we are told it is for 'everyone that's checking in.'

Despite going to great lengths to control what leaks, it has become a nearly impossible feat for a reported guest list of 1,000 attendees on Friday.

Several of the celebrity pals who made the cut have already been , including British talk show host Graham Norton and Ed Sheeran.

In the months leading up to the big day - and particularly this week - every detail from the  has become public knowledge.

Not only are Swift and Kelce's guests feeling the pressure, but the bride herself has in anticipation of what's to come.
