Adrianne Haslet-Davis continues to make progress, almost six months after being fitted for a prosthetic leg.
The Arthur Murray Studio dance instructor, 33, who was featured in a segment on last season’s Dancing with the Stars, lost a limb during the April 15 Boston Marathon bombings and has documented her recovery on camera on Anderson Cooper 360.
Six weeks after the tragedy, she cried as she held on to her replacement leg.
“This is like seeing my child walk for the first time again,” her mom said on video, just before Haslet-Davis stood up on her own. “It’s pretty emotional and it’s pretty exciting. But she’s a star. She’s amazing.”
