The One Direction heartthrob - who split up with dancer Danielle Peazer in May - has recently started a relationship with Sophia Smith, who he has known since they both attended St. Peter's Collegiate in Wolverhampton.
Speaking to Liam after the launch of the band's new movie 'This Is Us', Yahoo! omg! asked Liam, "You've got a girlfriend?", to which he replied, "Yep it's new.”
The website then questioned the 19-year-old singer further on his romance, asking: "What's this about you having a new girlfriend?", prompting Liam to point out the pretty brunette, saying: "Yes yes I do. she's sitting right over there. It's not been long."
Things are said to be so serious between Sophia and Liam, he flew her out to Los Angeles to join him when One Direction played four nights in the city earlier this month.
A source said: "Liam has really fallen for her. It's getting very serious, very fast. She's a sweet normal girl who likes Liam for who he is, not because he's in the most famous boyband in the world."
Liam dated Danielle off and on for three years and was linked to singer Leona Lewis during a break in their relationship.
