Things are certainly heating up between these two!!
The newly formed pair were snapped getting cuddly on the back end of the carpet, before entering the Shrine Auditorium for the big event!
Witnesses saw Nikki and Ian's arms wrapped around each other, as they stole kisses in between conversation…
Which is SO ADORBZ!
These two lovebirds are out and proud!! And we can't help but confess their happiness is contagious!
