Lourd and Rydell were romantically involved when they were younger, but as People mentions, they didn't rekindle their relationship until October 2017! 

Prior to that time, Lourd had been dating her Scream Queens co-star Taylor Lautner. Lautner had provided emotional support to Lourd after she lost her mother Carrie Fisher and grandmother Debbie Reynolds in December 2016. 

But in 2017, Rydell even joined Lourd and her family during their family trip to Norway on the anniversary of Fisher's death. People shares that the pair— along with Lourd's father Bryan Lourd and his husband, Bruce Bozzi— saw the Northern Lights while they were there.
