The 33-year-old model, who says estranged husband Tom Williams has been trying to win her back, wore a black top with matching jeans and a leather jacket for the occasion.
While Nicola and her boys seemed to be enjoying themselves at the bash, the former I'm A Celebrity, Get Me Out Of Here! contestant revealed that they'd had a few hiccups beforehand.
"Trying to get out the house for the Disney store event and Rocky lives up to his name and gives his brother a black eye playing catch!" she tweeted earlier in the evening.
Nicola has been putting on a brave face since her marriage to retired footballer Tom Williams broke down earlier this year.
At the time, she told Reveal: "I've known my marriage has been over for months, but I've been fighting it. I'm the lowest I've ever felt.
"Everyone sees me as a strong, hard-faced bitch, when actually I'm just an insecure girl who wants her marriage to work."
But despite being linked with various women, Tom appears to have had a change of heart has reportedly asked Nicola to consider giving their marriage another go.
