The news comes after it was recently reported Emma and Garrett were "surprised, shocked and happy" to be expecting a baby together.

Another source added: "[They are] surprised, shocked and happy at the same time, and so are their families."

Emma was first rumoured to be expecting a baby in June, and just a few days later, the news was seemingly confirmed by her mother Kelly.

When one fan asked on Instagram if Emma was pregnant, Kelly simply replied: "Yes!!" And when another said she would make "an amazing grandmother", she responded: "Thank you so much! Very excited."

Emma and Garrett were first romantically linked in March 2019 when they were spotted holding hands in the Silver Lake neighbourhood of Los Angeles.
