Two Pop divas. One night. One dress.

Whitney Houston and Madonna were both spotted at separate venues in Europe this week wearing Dolce & Gabbana's leopard print dress.

Whitney Houston launched her musical comeback in London on Tuesday at a listening party for her new album "I Look To You" wearing the saucy silver and black frock.

According to the Daily Mail, Houston was given the $2,200 dress to celebrate her first album in seven years.

Meanwhile, in Milan, Madonna was seen donning the identical knee-length number for her dinner with designers Domenico Dolce and Stefano Gabbana (in addition to the singer's man, Jesus Luz, of course).
