Both stars attended the Carrera Sunglasses Escape party, where they indulged in manis and pedis (no polish for Sebastian, natch). E! even says post-Glee, Dianna is considering getting a place in New York and splitting her time between the Big Apple and L.A.
Dianna parted ways with rumored boyfriend Alex Pettyfer in February.
