As well as a cake emoji that pops up next to your username - handily reminding everyone to wish you a happy birthday - each snap is greeted with a shot of celebratory confetti.

The new features have to be enabled manually in 'settings' by selecting the 'birthday' option.

Similar to Twitter's birthday update in 2015, Snapchat are expected to benefit from the new additions as the extra personal information is valuable data when it comes to advertising.
