Adam Lambert has admitted social media can be his ''worst enemy''.

The 36-year-old singer insisted it's vital aspiring stars stay ''true'' to themselves and though sites such as Twitter and Instagram can be an invaluable promotional tool, it's important not to focus too much on them or pay attention to comments and messages.

He said: ''It's a tough world out there, but it's important that you remain true to yourself, otherwise there's no point in doing it.

''Social media can be your best and worst enemy but you just need to do what you can do. I have learned not to read the replies or the hate.''

Adam shot to fame on 'American Idol' in 2009 and though he thinks some reality TV is OK, there are a lot of programmes he believes are just a ''waste of time'' because they ''glorify mediocrity''.

He told Client magazine: ''Reality TV isn't all bad - I came from a reality show in a way, but it was talent based.

''I personally find other reality genres to be a real waste of time - glorifying mediocrity and the mundane.

''It's really about doing what works for you and understanding who you are and what does work for you, and not getting lost in the noise!''

The 'Whataya Want From Me' singer admitted he experienced a ''backlash'' over his flamboyant persona when he began his career but he thinks there has been a ''huge improvement'' in the representation of the LGBTQ community in the music industry.

He said: ''Obviously there's still a long way to go, but there is a huge improvement. 10 years ago, there weren't many openly gay pop artists, and in a lot of ways people weren't ready and I got backlash when I wasn't really expecting it - I was just being myself and of course sometimes you do these things to prove a point more than anything.

''Now though, there's so many pop artists who are proud of their sexuality and the sheer number of us has improved the landscape.''
