Julianne Hough's new romance is getting serious.

The 'Safe Haven' actress - who split from 'American Idol' host Ryan Seacrest in April after almost four years together - brought her new boyfriend Ari Sandel to meet her close friends at actress Cara Santana's birthday bash in the Chateau Marmont in West Hollywood on Saturday night (17.08.13), according to gossip website JustJared.com.

Following their night out, Julianne tweeted: ''Aahhhhh... My Bed!!! I Love you... Good night y'all xoxo (SIC)''

The couple were first linked last month after the Oscar-winning director attended her 25th Gatsby-themed birthday in Los Angeles and were also spotted all over each other days later while having dinner in Nobu.

Ryan, 38, and Julianne are believed to split because he 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.''

It was recently revealed Ryan has moved on with 27-year-old South African beauty Dominique Piek, who is also newly single after ending her one-year relationship with 'Star Trek Into Darkness' actor Chris Pine in April.
