5 Things You Didn't See on TV at the 2015 Grammys

The Staples Center is a very big place.

So there was no way there were enough cameras to catch everything that went down last night at the Grammys.

But there's no reason to have a major #FOMO meltdown because we had our ears and eyes open for ya.

Here, we give you five things you didn't see on TV during the 2015 Grammy Awards...

1. Beatle Juice: As producer Ken Ehrlich was giving the audience some last minute instructions (No filming allowed on your cellphones! Please take off your red horns after AC/DC's performance and keep them off!), he was caught off guard by someone walking on the stage. "Excuse me, do you have a seat?" he cracked, before announcing, "Paul McCartney, ladies and gentleman!"

2. Seeing Is Believing: Speaking of McCartney, he went over to say hello to Taylor Swift during a commercial break. The "Shake It Off" singer asked a photographer if he got a shot of them together. Sadly, he didn't. Here's hoping Swift scored a pic later in the night.

3. Last But Not Least: Two of the last people to make it to their seats were BFFs Lady Gaga and Tony Bennett. Perhaps they got caught in the mess at the end of the red carpet, where several celebs like Pharrell, John Mayer, Chris Brown and Katherine McPhee had to wait in the crush of a crowded line to get their photos snapped before finally making it into the Staples Center. Seriously, it was like being in a crowded subway car with no air-conditioning.

4. Pre-show Jitters: Madonna may be a seasoned pro when it comes to to the Grammys, but even the original Material Girl gets nervous before a big performance. Madge was apparently telling some friends before she hit the stage for "Living for Love" that, yes, she was nervous about performing her new song, according to a source. (Don't worry, Madonna—you did great!)

5. Friendly Competition: We all know how Kanye West feels about Beck winning album of the year over Beyoncé. But if Bey had any beef with the alt-rocker going into the show, Jay Z didn't let it show. With Blue Ivy by his side, the "Hard Knock Life" megastar chatted with Beck backstage just minutes before the show began.
