Erica Mena -- Heartbroken Over Amber Rose/Wiz Khalifa Breakup


"Love & Hip Hop" star Erica Mena is taking the Amber Rose/Wiz Khalifa split hard, but she says the news has taught her something she plans on using to protect her relationship with fiancé, Bow Wow.

Mena, who says she is good friends with Rose, was out in the Bronx Wednesday and told our photog she always considered Amber and Wiz to be hip-hop royalty ... just a notch below Beyonce and Jay Z.

But Mena said she's learned a lesson from their split ... she's about to become an undercover lover.
