Chrissy Teigen has documented her 33rd birthday celebrations on Twitter. 

The American model - who is an avid tweeter - has given her followers a behind-the-scenes insight into how she and her husband John Legend celebrated her big day in Cabo San Lucas, Mexico. 

In a series of tweets about her birthday, Chrissy - who also revealed her appreciation of Ariana Grande's 'Mean Girls'-inspired music video for 'Thank U, Next' - wrote: "today has been very special. the thank you, next video "also my birthday. (sic)" 

The model - who has been married to the musician since 2013 - then quipped: "42 feels good "John won't let me go to dinner in my towel even thought it is my favorite outfit (sic)" 

Chrissy subsequently posted a video - which was shot by John - of her running to a dinner table on a beach. 

The star - who is seen sporting a bathroom robe in the video - later tweeted: "marriage  "just the bickering part (sic)" 

Chrissy's final birthday-themed video was of a bed covered in rose petals with a big love heart in the middle. Chrissy - who officially turned 33 on Friday - says in the clip: "This ... feels like a lot of pressure." 

Meanwhile, Chrissy recently revealed sees Twitter as her "connection to the world". 

The model shared: "People are like, 'Why do you have time for all of these strangers?' But that is my outside connection to the world. "I genuinely love doing it. I always have. I enjoy talking to people and feeling like I know them and having this conversation." 

Chrissy briefly abandoned Twitter after she received threats following a message she posted about gun control, but she eventually decided to return to the platform. 

She explained: "Our lives would be so much easier if we didn't dabble in politics at all, but I don't want that kind of life. For us, we are willing to take that risk, because we believe in it so passionately."
