Emma Roberts and Evan Peters are ''happier than ever'' together.

The 'American Horror Story' actress, who got engaged to her co-star in December 2013, sparked rumours their relationship was on the rocks after she was spotted out multiple times without her engagement ring over the past few weeks.

But a source said: ''Emma and Evan are still together and happier than ever!

''Emma has been known not wear her ring all the time.''

The couple - who started dating in 2012 - recently celebrated the one year anniversary of their engagement on holiday with friends.

The insider told E! News: ''The couple spent their New Year's on a ski trip with a group of close friends.''

News that their relationship is still solid comes just weeks after another source claimed Evan, 27, and Emma, 23, were fighting a lot on set.

The source told OK! magazine: ''Emma and Evan are making out - that is, if they're not screaming at each other.''

Evan admitted last year and he and Emma were in no rush to plan their wedding.

He said: ''No, we're just enjoying being engaged right now. I'm very happy right now, thank you.''
