Is model falling for another rapper?

Is undefinedfalling for another hip-hop star just after revealing she's hoping for a reconciliation with her estranged husband, Wiz Khalifa? It's looking like it.

The 31-year-old model was spotted hand-in-hand with rapper Machine Gun Kelly (real name Richard Colson Bake) as he arrived to pick her up from the airport in L.A post her UK club tour.

Amber was seen rubbing her big behind all over the rapper's crotch as she made her way past security.

The mother-of-one donned a skin-tight sheer bodysuit as the rapper squeezed up behind her as they waited to collect their luggage.

The funny thing is Machine Gun Kelly has links to Wiz; the pair worked together on 2013 track Mind Of A Stoner.

Neither Amber nor Machine have confirmed if they are dating.
