'Trespassing' superstar Adam Lambert has been praised by American Idol's very own Randy Jackson (pictured far right) for his phenomenal ability as a singer.

Jackson, who is a judge on the popular talent show that helped Lambert on his rise to fame back in 2009, took to social networking site Twitter earlier this evening (April 30) and congratulated the vocal sensation on his recent Jimmy Kimmel performance:

"Loved seeing @adamlambert on @jimmykimmel one of our best contestants ever!!!"

Lambert, who treated fans to a stunning rendition of 'Never Close Our Eyes' on 'Jimmy Kimmel Live!' last week, responded by writing: "Thanks Randy!!! ;)"
