Github integration with Gitlab CI


We are using both CircleCI and Gitlab CI, and we’re wondering if there is a way to integrate GitlabCI with github in the same way CircleCI does it.
The main feature we would like to have is the update of tests in the pull requests.

Is there a way to do this with GitlabCI?
We would like to keep using Github, and GitlabCI is awesome, but that integration is quite important so would be great to have it.
Even if it’s through a third party integration.
