Instagram now allows you to add a pal to your live broadcast
To add a friend to your broadcast, tap on the icon on the bottom right that shows two faces together. Tapping that icon will pop up a list of your Instagram friends who are watching you live. Select one of them and click on add to invite him or her to join your live feed. If your friend accepts, you will see his or her image in a split screen directly underneath you. At anytime, your friend can decide to exit stage left and disappear from the live feed. Or you might decide to replace your pal with the boring personality for the one who is always bubbly and eager to perform. Once your live broadcast is over, you can share it to stories, or hit Discard to remove it from your device, the app and your mind forever.
If you want to catch one of your pals in a live broadcast with a friend, you'll see two circles meshed together in your stories bar at the top of the display. You can tap on the circles to view your pals' live broadcast. The update containing this new feature can be found in version 20 of Instagram available from the App Store or the Google Play Store.
