"Twilight" star Taylor Lautner and Marie Avgeropoulos have broken up after being together for a year and a half!

According to E! News, the "Tracers" co-stars decided to part ways a couple of months ago. A source reportedly told the publication that the breakup was "completely amicable."

"Taylor is dating and having fun. Nothing serious," the insider added.

According to Daily Mail, however, the pair was spotted holding hands outside a restaurant in Venice just last Tuesday.

They never really spoke about their relationship in public but were photographed several times over the course of their time together.

This news, however, comes a month after Radar Online allegedly spotted the "Abduction" actor around the vicinity of two known LGBT hotspots in West Hollywood, The Abbey and Mother Lode. He even reportedly posed with gay model Murray Swanby for an Instagram photo.

In early 2014, he was also accused by Defamer of using "X-Men" director Bryan Singer as a "launching pad" for his career.

Was Taylor Lautner and Marie Avgeropoulos' breakup affected by the rumors surrounding the heartthrob's sexuality?

Based on Lautner's list of ex-girlfriends, however, those rumors are a bit hard to believe. Prior to meeting Avgeropoulos on the set of "Tracers," he publicly dated several other starlets.

He was linked to his "Abduction" co-star Lily Collins as well as pop star Taylor Swift, whom he met on the set of "Valentines' Day." He was also romantically connected to "The Heart Want What It Wants" singer Selena Gomez.

Avgeropoulos, on the other hand, dated her "I Love You, Beth Cooper" co-star, Shawn Roberts, before Lautner.

Despite breaking up, the pair will still have to see each other when they promote "Tracers" in March. They reportedly started dating after meeting on the set of the said movie.

Avgeropoulos is currently playing Octavia Blake in the CW's post-apoloyptic series, "The 100."
