Katie Holmes sunglasses scarf gym mini cooper

Katie Holmes couldn't stay away from the gym one day longer!

As soon as the fitness queen returned home from visiting hubby Tom Cruise on the Miami set of his new film, Rock of Ages, it was back to the grueling daily workout regime for Kate!

Armed with java in hand, Holmes popped into her Mini Cooper with a big smile on her face, looking very happy to be back home in LA.

Holmes' hard work and dedication at the gym is definitely paying off; she looked absolutely flawless frolicking in her bikini on the beach last week!
