Jennifer Aniston isn't "interesting" enough to be on social media.

The 'Mother's Day' actress - who is married to Justin Theroux - has no desire to join public sites such as Twitter or Instagram as she finds simple text messaging is all she needs to communicate.

She said: "I can't think of anything interesting enough that I would want to put out there...I just text."

When she does text, the 47-year-old actress is a big fan of emojis and Bitmojis and as well as her own personalised cartoon avatar, she loves creating them for other people.

She told E! News: "I love me a good emoji.

"I love Bitmojis. I like to make people's Bitmojis."

When her 'Mother's Day' co-star Jason Sudeikis jokingly called her an "artist" for her digital design efforts, she added: "I am. That's what I'm good at."

Despite her own years of success, Jennifer admits she was intimidated on the set of 'Mother's Day' by co-star Julia Roberts and was so in awe of the 'Pretty Woman' actress, she messed up one of their scenes.

Asked why she felt intimidated by the star - who she had known before working with her on the ensemble comedy - she told 'Entertainment Tonight': "Because it's Julia Roberts! Oh my gosh!

"It's just a different thing when you get to work with them and then you're doing what you both do, [but] together.

"I even flubbed in the first take and called her Julia!"
