The 19-year-old stepped out in one of her trademark skintight, low-cut mini dresses on Thursday evening (21 November) to attend a pop, fashion and sport party with her publicist.
Courtney split from husband Doug Hutchison, 53, earlier this month, saying she wanted to explore her freedom after marrying at the tender age of sixteen.
Well, she certainly looked to be having fun last night!
Clad in a skimpy LBD, Courtney vamped up her party look with red lipstick, scarlet nails and mega-watt lashes. She also flashed her matching black and red underwear at some stage. Oops.
She spent the night chatting with publicist Edward Lozzi.
Courtney recently admitted that her stint in the Celebrity Big Brother house during the summer (which included some flirtatious behaviour with housemate Mario Falcone) had sped up her separation from Doug.
The couple married three years ago when Courtney was 16 after meeting via an online acting workshop run by Doug.
She recently said: "I'm really, really wanting to focus on me. I want to clear the air a little bit and put it out there that I know I need to be 19. I need to do what regular girls do."
Despite the split, however, Courtney and Doug are still living under the same roof for now and he's continuing to-manage her career.
Talking to FOX411, she said: "What part of this venture hasn't been unconventional, you know? It's extremely unconventional to live in the same house as your soon-to-be-ex. Especially with a joined business venture together, it's quite uncommon, especially in Hollywood with the spotlight.
"It's been working out okay...it's fairly new so I don't know what the future has to hold but I hold hope in my heart that we can prevail and remain close because through the transition of our marriage and realising we aren't meant to be together romantically, we realised we made better friends than partners in that sense."
