Halle Berry reportedly spends $10,000 a month on her breasts.
The 49-year-old actress has ruled out plastic surgery but allegedly keeps her cleavage looking good with an extensive beauty regime.
A source told RadarOnline: "She spends a good $10k a month on her décolletage and it pays off.
"Halle has laser resurfacing and vein treatments, plus she uses Crème de la Mer on her neck, chest and cleavage.
"Then there's firm boosting creams and exfoliation, plus she does loads of pushups and chest-strengthening exercises. Halle looks fantastic and she's proud of the fact she achieves her looks without the help of a surgeon."
Halle previously admitted she felt under pressure to have plastic surgery.
She said she is often encouraged to go under the knife to maintain her youthful appearance and claims cosmetic procedures are "like crack" in Hollywood.
She said: "It is pressure. When you see everybody around you doing it, you have those moments when you think, 'To stay alive in this business, do I need to do the same thing?' I won't lie and tell you that those things don't cross my mind, because somebody is always suggesting it to me. It's almost like crack that people are trying to push on you. That's what I feel like."
