The couple, who married in September, seem to spend most of their time in New York, but the couple have been in Los Angeles for a week and a half while Justin is working on new studio music.

Thanks to the success of his current collaborative single, the pop sensation has become one of the most dominant musicians of his time.

According to Forbes, he currently owns 15 top 10 singles, and he is tied with Bruno Mars for the fifth highest number of hits, as well as for the second biggest song of a male artist.

Justin also holds the impressive record (possibly frustrating) of the highest number of debuts in second place in the charts, with four songs initially reaching that position.
