It all started when the actor's recent vacation photos caught they eyes of the red-headed starlet on Thursday.
As The Blast reported, Liam escaped on a mini vacation with friends and family after filing for divorce from Miley Cyrus.
Fans weren't the only ones to notice how happy he looked, and Lindsay took the opportunity to slide into the comments.
Replying to photos of Liam and his married brother, Chris Hemsworth, LiLo asked why they didn't hang out when she was in Australia.
"Why did we meet in Sydney or Bondi?" she wrote.
Fans can't handle it.
While there are mixed reactions floating around, tons of people are here for the duo!
"Plz keep us updated on the progress of this," wrote one fan. "I'm conflicted but I completely support this at the same time," added another.
Some are just giving LiLo props for her confidence.
"Can't say I blame her for trying," a commenter replied. "From Miley Cyrus to Lindsay Lohan.. seems like a reasonable rebound," wrote another supporter.
Not everyone is living for a Liam/ Lindsay hookup.
"Liam's upgrading, & you sis are not that," one hater wrote. "Liam doesn't need another trainwreck right now," said another.
Some fans are even pleading with Lindsay not to take things any further.
"Lohan please stay away from Hemsworth," they commented.
Liam filed for divorce from Miley last month and things between the two are wrapping up soon.
As The Blast reported, Liam and Miley have been hashing out details for the end of their short-term marriage and sources close to the couple tell us their divorce settlement will be done by Halloween.
