Ryan Seacrest and Julianne Hough want to get married.

The smitten 'American Idol' host has been thinking about settling down and starting a family with his girlfriend of two years, describing the actress-and-dancer as ''phenomenal''.

Quizzed on Chelsea Handler's talk show, 'Chelsea Lately', if he wants to tie the knot and have a baby, he said: ''We both do.''

But Ryan, 38, insisted the 25-year-old beauty would be the first to know when he was ready to make a commitment to her, not the talk show host.

The loved-up TV star continued to gush over his 'Dancing with the Stars'-winning girlfriend - whose brother, Derek, is also a professional dancer - when a picture of the pair walking the red carpet at the Golden Globe Awards appeared on screen.

Ryan added: ''She's so beautiful ... stunning. She's the best part of every day.''

Julianne has previously admitted Ryan was her ''first celebrity crush'', but was hesitant to go out with him when they first met.

She said: ''I'm kind of dating my first celebrity crush, so I feel pretty fortunate.

''I was reluctant because he is such an influential guy and what if it didn't work out? Our first date, I was so nervous that I just sat there and interviewed him with questions like, 'Are you loyal?' and, 'Are you close to your family?' ''
