Australia celebrate with the Urn after Australia drew the series to retain the Ashes
Australia lost the Test match by 135 runs meaning they drew the five-match series 2-2.
But the loss did little to dampen spirits because a draw was enough for the baggy greens to retain the Ashes after they won in 2017-2018.
Miss McCarthy has been in the UK supporting her boyfriend Nathan Lyon throughout the series.
She shed tears of joy when Josh Hazlewood took the final wicket of the fourth Test in Manchester as Australia retained the Ashes in England for the first time since 2001.
Lyon split from his previous partner and mother of his children Mel Waring at the end of 2017.
Miss Waring took to social media last week to say she was not jealous of Miss McCarthy's relationship with Lyon.
Eagle-eyed fans also noticed Lyon's girlfriend of two years Miss McCarthy donned a 'N' necklace while dressing up in the glamorous white gowns with fellow WAGs.

The fifth Test finished with Root, who had the haunted look of a beaten captain before this final Test, flinging himself to his left to catch Josh Hazlewood and give his side the 135-run victory.
Australia never really looked like getting near their formidable target of 399 to win the series as well as retain the urn but how hard they made England work for a victory that was sealed just after 6pm by two catches by Root off successive Jack Leach deliveries.
And how brilliantly the unlikely and spiky figure of Matthew Wade played to make his second century of this Ashes before he finally became the eighth wicket to fall trying to lift Australia somewhere close to what would have been the fifth greatest chase in history.
