Nicholas Belton performs double duty in one of Broadway's biggest hit musicals, Natasha, Pierre, and The Great Comet of 1812. Belton plays the dual roles of Prince Andrey (a solider in the war and the fiance to the title Natasha) and his father, Old Prince Bolkonsky (an eccentric old Russian).

BroadwayBox recruited Belton (who also curates the lifestyle blog Sunday Theory) to take over the BroadwayBox Instagram on Saturday, February 4 and give followers a glimpse of life behind the scenes during a two-show-day at The Great Comet. Scroll on for the fun backstage pics and videos.

Headed to work with my piping hot Plum Almond Tart! I'll share a video taste test once I get to the theatre. #GreatCometTakeover

My mornings don't usually start with baking confectionery treats. Right when I wake up I head to the gym for a quick workout to wake up my mind + body. Every morning without fail, I blitz up some sort of green smoothie. Today it looked like this. How do you start your day? #greensmoothie #coffeelater #GreatCometTakeover

@GreatCometBway fight call Powder Puff vs Little Joe. Fight call is when we rehearse the fight scene & go over our movements before the show. #safetyfirst #GreatCometTakeover

At the beginning of Act 2 we all pass out #LoveLetters to audience members so our intermission is spent being creative. I love drawing so I have so much fun doing these! Raise your hand if you've received one of my letters at @greatcometbway #WeWriteLetters #GreatCometTakeover

After saying Hi at the stage door and grabbing some food I often do some work in my dressing room in between shows. I have a blog called @sundaytheory_ and love sharing my recommendations from recipes to travel spots to healthy living ideas with all of you. Listening to music and writing is a great way to get my mind off of other things (like my mic going out during my last song today PS thanks for all the kind words. Hopefully it wasn't as bad as I thought. Ah well, that's live theatre for ya!) Today I just posted my '5 Favorite Date Night Spots in Midtown NYC'. Check it out if you're looking for a unique cocktail and bite to eat before or after seeing @greatcometbway! #GreatCometTakeover

I'm a mover + a shaker and just don't do well being sick so I eat as clean as I can to keep a healthy gut. Look up how your gut is like your "second brain" and influences your well being. Tonight's dinner is spaghetti squash salad with chickpeas, brussels sprout slaw, and herb dressing from @twoforksnyc What are you guys having for dinner? #GreatCometTakeover

Show time! Thanks for all the awesome takeover request on my twitter! I know a lot of you wanted to see my quick changes backstage but the problem is they are really quick and I don't have much time! I'll try to get some more backstage footage for this 2nd show. For now - places! #AndreyIsntHere #GreatCometTakeover
