It's the downside of being a power couple.

Justin Bieber and Hailey Baldwin got mobbed by fans at their hotel and then by photographers on their way to church last night, but they were gracious enough to pose for pics outside their hotel so that everyone could get a good glimpse before they went on their way.

The two are planning their wedding, and apparently The Biebs has made it clear that money is no object when it comes to their nuptials!

"Neither Justin nor Hailey want a flashy showbiz type wedding, because they want the day to be about them and their love for each other, and not just a huge celebrity packed party. Hailey’s dad Stephen [Baldwin] offered to pay for the wedding, but Justin insisted on paying for it himself. He’s made it clear to Hailey that money is no object and whatever she wants for the big day she can have," a source dished to Hollywood Life.

"Hailey is absolutely loving planning the wedding. She’s dreamed about this moment since she was a little girl, and now all her dreams are coming true. The fact she gets to walk down the aisle with Justin is more than she ever could have hoped for," the source added.

The lovebirds ran into JB's old flame Kourtney Kardashian at services, so hopefully that didn't cause any tension!
