Ryan Seacrest and Julianne Hough are taking their romance public after much speculation that the two are dating.

In recent weeks, the 35-year-old American Idol host and the 21-year-old former Dancing with the Stars pro turned country music singer have been spotted around Los Angeles looking like more than just friends.

"Things have gotten more serious over the last month," a source tells PEOPLE. "They're perfect for each other."

Another source claims Ryan has also visited Julianne in Nashville, but didn't want anyone to know "because their relationship is still in its early stages and Ryan really, really likes her."

Ryan has frequently mentioned Julianne on his KISS-FM radio show -- so much so that co-host Ellen K teases him about his "crush."
