Something that Rihanna should have taken on board last night for her gaping neckline.
Because her cleavage just about stayed in place inside the lacy neckline as she leaned over to greet some famous friends at a charity gala in New York
As she leaned in to say hello to David Bowie and his wife Iman, she almost gave a little too much away.
Rihanna, 23, arrived at the 5th DKMS Linked Against Leukemia gala at the Cipriani Wall Street venue.
She looked stunning in a long lack gown, but as she posed for photos, she almost gave the game away beneath the dress's plunging neckline.
And thankfully, as she stooped to chat to the famous singer and his model wife, her cleavage stayed in place as she bend over to shake Bowie's hand.
Rihanna was a guest of honour at the event where she was honoured for her dedication and fundraising work in the fight against the disease.
She said: 'Anyone can be affected by leukemia. It is the number one disease children in the U.S. die of and we can change that.
