Beyoncé's line with Adidas is reportedly struggling, driving home the challenge of filling the $2 billion hole left by Kanye West's Yeezy line

• The Wall Street Journal on Wednesday reported sales for the singer's Ivy Park Adidas line fell 50%. 
• Adidas' struggles to gain traction with Ivy Park come after the brand cut ties with Kanye West.
• Beyoncé's contract with Adidas expires after 2023, according to the Journal report.

Beyoncé on Sunday became the most-decorated artist in Grammys history. On Wednesday, a less-stellar Beyoncé headline appeared in the Wall Street Journal.
