Britney Spears seeking marriage proposal from boyfriend Sam Asghari

American singer Britney Spears is awaiting to tie the knot with her longtime boyfriend Sam Asghari, according to circulating rumours.

Reports revealed that the Toxic hit maker wants her boyfriend of four years to pop the question in front of her.
