It’s been almost three years since Vanderpump Rules sweethearts Katie Maloney and Tom Schwartz got hitched, but Lance Bass has now dropped a huge bombshell about the validity of their union.

During a recent interview on the REALITY BYTES! podcast, the former 'N Sync member raised some questions about whether or not the pair are in fact legally wed, due to paperwork concerns.

'We just found out Tom and Katie are not married,' Bass, 40, said in the podcast. 'They did not send in their materials right, so, they are not married.'

The happy couple? Katie Maloney and Tom Schwartz, seen here in November 2018 at the People's Choice Awards, may in fact NOT be legally married, according to Lance Bass

Bass, 40, officiated the Vanderpump Rules nuptials of Brittany Cartwright and Jax Taylor last month.

He brought up the questions about Maloney and Schwartz on the podcast while discussing how nerve-wracking it can be to file marriage paperwork properly and legally.

Maloney, 32, acted as Matron of Honor at Jax and Brittany's Kentucky wedding, while Schwartz, 36, shared the honor of best man with Tom Sandoval.

Costars Kristen Doute, Scheana Shay, Lala Kent, Stassi Schroeder and Ariana Madix made up Cartwright’s team of bridesmaids.

Lance, a singer who is also famous for being a super-sized reality TV fan, alluded to the fact that Katie and Tom's wedding conundrum might be fodder for next season's storyline of Vanderpump.

Katie's 2016 wedding to Tom took place in a forest in Northern California, officiated by Lisa Vanderpump herself.

The pair have yet to comment on Lance's weighty allegations.
