OPI Serena Willians Glam Slam

No Im not talk about the one release already but 2 new ones. I found these on Mbeautylonge. Does anyone know if this site is legit. I've never order from it but its tempting me. Anywho, as you know Serena teamed up with OPI to make the first set (which im still waiting for) It had the Green Shimmer plus the new famed black shatter.
Well heres what in store for us now and I think I like it.

Spark de Triomphe Polish and White Shatter

The gold glitter above reminds me of the same type of glitter that the Justin beiber purple glitter has. It said that these should release in April. I'm excited already!!!
