Two political activists tied the knot while blockading Westminster Bridge in a protest against climate change.
The unique nuptials were held on Tuesday amid huge Extinction Rebellion protests around London.
Tamsin Omond and partner Melissa were married surrounded by protesters on the famous bridge.
"Thanks to Extinction Rebellion this beautiful wedding is happening right now in the middle of Westminster Bridge," wrote fellow activist Rupert Reed on Twitter.
"So happy to witness my friend and longtime comrade Tamsin Omond marrying in this unique way."

Video of the event shows the happy couple embracing as protesters cheer. A priest dressed in white applauds the pair.
"My friend just got married in the middle of the rebellion and if this doesn't go down in the history books then wtf," wrote activist Sam Knights.
More than 130 people have been arrested throughout London as a result of the protests, reports Metro.
This week Extinction Rebellion will target 60 cities across the world to protest climate change.
