Justin Bieber Serenades, Smooches Hailey Baldwin amid speculation about marriage

Justin Bieber and Hailey Baldwin are currently in the eye of the storm of wedding rumors, but they are also in the eye of London.

The soon-married couple was spotted on Tuesday. They lined up for the London Eye Ferris wheel – like everyone else – and eventually reached the top. Once they were alone, the Biebs and Hailey closed their lips as if there was no tomorrow.

After the party, Justin released a guitar and put his element in Hailey's serenade in front of Buckingham Palace. She looked like doe and hit by the romantic gesture of her boyfriend.

Justin professed his love for Hailey as he sang in front of the crowd that was naturally gathering around them.

It's kind of their thing lately right here, The … and pretty much everywhere else.

The international trip takes place on the heels of Bieber and Hailey hitting a court in New York last week for get a marriage license. Many people – including Hailey's uncle, Alec Baldwin – Think that they have already gotten involved, but we are told it's just that no.

However, they may be heading early enough to the altar, especially since they now have their marriage license. Sources told us that they would be tie the knot out of the country … and they are definitely not in the United States.

Stay tuned …
