The EastEnders actress, who plays Lauren Branning, stole the show in her sexy black dress as she attended the glitzy awards ceremony at London's Hippodrome on Monday night (3 October).
Not that she needs an award to make fiancé Dan Osborne proud! The former TOWIE star tweeted last night: "Very proud of her with or without an award. Knew she would win anyway, she's fricking gorgeous."
Jacqueline attended the awards bash without Dan, who was no doubt at home looking after their adorable baby daughter Ella, one.
The couple welcomed Ella in February last year, and then became engaged during the summer when Dan popped the question during a family holiday abroad.
Jacqueline returned to EastEnders earlier this year following maternity leave. She wasn't the only Enders star to scoop a gong on Monday night: Lacey Turner (Stacey Fowler) and Steve McFadden (Phil Mitchell) took home acting prizes, while Tameka Empson (Kim Fox Hubbard) was named 'Funniest Female' and Dame Barbara Windsor won 'Best Exit' for Peggy Mitchell's death storyline.
