The two yummy mummies stepped out in the capital on Thursday (17 October) to watch their actress pal Angela Griffin on stage in her latest role in 'One Man, Two Guvnors' and they both looked glam for the occasion.
Myleene stood out in a figure-hugging red dress with bejewelled detailing around the shoulders and sported a pair of simple black, T-bar heels.
She also carried a small black handbag and styled her hair in a messy side plait.
The mother-of-two looked pretty covered up last night in comparison to her recent risqué outfits.
Earlier this week, 35-year-old Myleene flashed her underwear in a sheer black dress at a glitzy bash and at the beginning of the month, she stepped out in a see-through silver gown to host the Classic BRIT Awards.
Well, we suppose she does have the figure for such bold outfits!
Britain's Got Talent judge Amanda looked smart and glamorous yesterday as she opted for an all-black ensemble.
The 42-year-old wore a pair of black skinny jeans, which she teamed with a black peplum top, black boots and a black winter coat with a furry collar.
After catching up with buddy Angela once she came off stage, Amanda let her one million Twitter followers know just how great the show had been.
She tweeted: "Loving The Play @Angela_Griffin is amazing. Whole cast shine!!"
And Myleene echoed Amanda's sentiments in her tweet, writing: "You were amazing @Angela_Griffin. @Amanda_Holden and me sooooo proud of you and the cast. X"
