A lunch with her nearest and dearest kicked off the proceedings on 18 July, a day before her 35th birthday.
And now Michelle and her family have made their way to the zoo for a picnic with one of her showbiz pals!
Joining the Liberty X star for her day of fun was 911 singer and fellow Big Reunion star Jimmy Constable, his wife Claire (who made Michelle's fab designer handbag birthday cake) and their adorable two kids.
Michelle's husband Hugh Hanley joined the gang at Whipsnade Zoo, and their children Faith, two, and five-month-old AJ completed the picnic party.
Wearing a pretty nude vest, Michelle tucked in to quite a feast with her guests.
Sharing a snap of the happy gang online, Michelle said: "Having an amazing time at @ZSLWhipsnadeZoo @claireconstable @jimmyconstable @hughhanley."
And she'd clearly been looking forward to the picnic.
The night before, Michelle said: "Night peeps. big day 2moz Family picnic with friends at the zoo! #bliss Might even pack a bottle of wine in the cooler #livinontheedge lol."
But, ever diligent, fitness fan Michelle had made sure she deserved her Saturday splurge.
Earlier in the day, she told her Twitter followers: "Legs day #upearlytotrain."
Now that's commitment!
BTW, Michelle's not the only star celebrating her birthday at the moment.
