Ryan Seacrest told friends he is ''single and loving it'' as he partied in a Los Angeles nightclub with a mystery beauty.

The 'American Idol' host split from his girlfriend Julianne Hough after almost three years of dating in April but he seemed to have put his heartache behind him as he joined other revellers at entertainment company SBE's Summer Sessions at XIV.

Ryan was overheard telling pals he has been ''loving it'' since he became single again, and he even took his gorgeous blonde companion into the DJ booth with him when he span tracks for 30 minutes.

A source told the New York Post newspaper: ''He was with a blonde throughout the majority of the day. He asked to go into the DJ booth, and brought his new arm candy with him, mixing tracks for 30 minutes.''

Ryan, 38, and Julianne, 24, are believed to split because the TV star - who has a number of different projects - didn't want to get married and take their relationship to the next level.

The professional dancer got tired of waiting for an engagement ring and so called the romance off.

A source previously said: ''He just wouldn't propose. However, Ryan was this close to looking for rings. Julianne is the only girl Ryan has allowed himself to get serious with.''
