The pair are close friends and the Lionness wished Scott well on her 39th birthday.
Scott has had a busy birthday week which included attending a swanky awards ceremony with her new partner Jess Glynn.
The presenter also posed with Williamson at the Attitude Awards and they stunned together.
The Arsenal defender has now taken to Instagram and shared several snaps and a video of Scott dancing, alongside a heartfelt message.
She wrote: “Happiest of birthdays to you my friend.
“Many more years of carrying your bag or your cape and always having a ‘however’ to argue against me.”
Scott and Williamson have become close in recent years and regularly enjoy partying together.
Earlier this month they enjoyed a night out celebrating Williamson being presented with her OBE by Prince William.
In the summer they both let their hair down as they partied in Ibiza with friends.

Scott has also been spending more time with new girlfriend Jess Glynn after The Sun last month revealed the couple began dating earlier this year.
They have enjoyed a series of dates before and after the Women’s World Cup.
And then earlier this month the couple partied alongside David and Victoria Beckham at their exclusive Netflix documentary premiere after-party at The Twenty Two in West London.
