I'll try and be classy and avoid saying she's wearing Mulvaney in those shots as if he's a piece of meat, but I may not succeed.
That was quite the publicity stunt, and really - this is too. GaGa (does she have a proper name? It feels rude to call her that.) has been thoroughly eclipsed, professionally. Her music isn't drawing attention to her, I cannot remember the last time she was mentioned at e.g. an awards ceremony.
Whilst this particular publicity stunt may endear her to some, mostly it's just that - a stunt. A predictably yawn-generating stunt.
I've seen it mentioned she and Mulvaney are both clients of the same agency (management agency, publicity agency, it didn't say). That's just a coincidence, I'm sure.
