The couple, who are currently undergoing IVF treatments to help Kourtney get pregnant, are said to be ‘praying for a miracle.’

‘[Kourtney] feels like she’s almost at the cut-off age of having kids, so this is almost like her last chance,’ a source told Us Weekly on Wednesday.

Travis ‘is fully supporting [Kourtney] every step of the way’ and the journey has only made the ‘very close’ couple even closer.

‘The journey just affirmed their bond and love for each other.’

The Blink-182 drummer proposed to Kourtney in October on the beach during sunset with her family watching on from the distance.

The pair tied the knot during a drunken Las Vegas wedding after the Grammys last weekend, but they are not legally married as they couldn’t get a license at the time.
