This past Wednesday, Apple surprised iPhone users with 300 new emojis. In hopes to obtain diversification, the easily scrollable list now contains options for expanded families, same-sex couples and skin tone modifiers.

Alexa Chung has a bit of advice for developers, too.

Elsewhere on Twitter this week, Colin Hanks plays fashion police, Taylor Swift slams the media, and Justin Bieber just wants you to be happy.
