Sarah, 31, is visiting the West Coast with her boyfriend Mark Foster and has had a great time visiting all the tourist hotspots.
Earlier this week, the Girls Aloud star and Mark went to Universal Studios in Hollywood and it seems they had a ball together.
Not only did the pair bump into some full-size minions from the hit film Despicable Me, they also rode a water ride and toured the studios.
Wearing a funky black baseball cap with a leopard print lining, Sarah posed for a photograph in front of a set from a disaster movie.
Tweeting it to his followers, Mark joked: "@SarahNHarding forgot to tidy up at @UniStudios yesterday lol!"
Meanwhile, on a more sombre note, the couple have also paid tribute to Hollywood icon Marilyn Monroe, who died aged 36 in 1962.
Sarah was pictured kissing Marilyn's crypt in Westwood Village Memorial Park Cemetery in Los Angeles. Sharing it with her fans, Sarah simply commented: "RIP xxx"
Earlier today, Sarah's Girls Aloud bandmate Nadine Coyle - who is based in LA - revealed that she is pregnant with her first baby.
Fellow GA star Cheryl Cole also jetted into LAX Airport last night. We wonder if they will meet up for a mini celebratory reunion?!
