So this is a common problem with windows phone where updates get stuck or whatever. Anyway I always forget the fix and this one seems to work. The skype update made me remember and I ended up having 9 updates I didn't know about.
Steps from AliGoneMobile: How to Fix Windows Phone App Updates Notifications on Store Live Tile
1. Find any app that has a pending update, and open it in the store do not update the app yet, just make sure your phone registers that there is an update available, then exit the store.
2. Unpin the Store live tile from your start screen
3. Soft reset your phone by holding the volume down and power button together for about ten seconds.- This will NOT delete any of your data.
4. Pin the store tile back to your home screen and wait. (it might take several hours for the first updates to appear, as the store doesn't constantly check for updates).
So for the new Icon owners give it a try.
