Christina Applegate is terrified her reconstructed breasts will pop out of her dress whenever she's at red carpet events, because she can't feel them.

The actress underwent a double mastectomy last year after she was diagnosed with breast cancer, and she had her breasts rebuilt and implants fitted.

Applegate is happy with her new bust, telling People.com, "I don't need to wear a bra. They don't hang down to my knees like they did before. They're pretty solid."

But she admits she's constantly terrified she's exposing herself: "The numbness is strange. I can't feel anything. I don't know if they're hanging out in clothes, so I need someone to make sure they're under wraps." (IG/PE/KL)
