'Shameless' star Emmy Rossum went on a double date with eccentric singer Lady Gaga and their respective boyfriends.
She said: ''We stayed in, cooked steaks, and watched 'Shameless'. It was all very normal, and she is so nice.''
Gaga was first to linked to Taylor late last year but has so far refused to confirm their relationship, saying: ''I would just say that I'm very happy - that's all I'm saying - I am happy I am very happy.
''All I will say is that I am wonderfully happy and more creative than ever.''
Emmy - who starred with Taylor in a couple of episodes of 'Shameless' - also spoke about her divorce from Justin Siegel and admits it wasn't easy at first.
She told InStyle Hair magazine: ''Everyone messes up in relationships and has peaks and valleys in their personal lives. When I realised it wasn't the end of the world and I would keep on standing, I knew it was going to be OK.''
