They have been going out for 4 months and it looks like they thought that was enough time for them to decide to spend the rest of their lives together.
The couple will get hitched in about 6 months. Will Katy have enough time to plan a wedding between all her concerts? We hope so. For the moment we know that Katy, Russel, 蕾哈娜 and Taylor 迅速, 斯威夫特 will all be going to the wedding. Congrats to the happy couple!
