Watch the bizarre moment Drew Barrymore covers Jason Kelce in flowers and hands him a belt at WrestleMania

Drew Barrymore showered Jason Kelce with flowers backstage at WrestleMania in Philadelphia.

The actress, Kelce, and his former teammate, Lane Johnson, were all guest celebrities in the WWE's two-night celebration through April 6 and 7 at Lincoln Financial Field.

After the event, a video of Barrymore, in character as Flower Power, meeting Kelce and Johnson backstage surfaced. She handed Kelce a gold WWE replica belt before covering him in flowers.

'I am Flower Power,' she said as she entered the room. Kelce played along with the character, saying: 'You look unbelievable.'

'Thank you very much,' Barrymore responded. 'Flower Power wanted to dress up to present you with this [belt] that has been all over the place. It was at the Super Bowl, but it needs to come home to you, Jason and Lane, and come home to Philly.'

The retired Eagles center accepted the belt and thanked Barrymore for delivering it.

'I love this, Flower Power, thank you for delivering the golden belt for WrestleMania,' Kelce exclaimed before they broke character. Barrymore was the first to break as she introduced herself and gushed over the former Eagle and veteran offensive tackle.

After exchanging introductions and hugs, Barrymore asked Kelce what his ring name would be, to which he responded 'Hybernating Jason.' After agreeing they would be a good tag team, Barrymore sprinkled the flowers on Kelce.

'The Rock gave me this fanny pack, and I'd like to just [sprinkle petals on Kelce,] she said while performing the playful ritual. 'Remember I told you you'd be surrounded in nature?'

'Oh, please sprinkle me,' Kelce said, laughing.

Kelce and Johnson appeared out of the stands in luchador masks during Rey Mysterio and Andrade's match against Santo Eskobar and Rey's son Dominik. With their identities hidden, Johnson grabbed a steal chair away from Dominik before Kelce threw him towards the ring post and back into the squared circle.

From there, Rey executed his '619' finisher and pinned Eskobar for the win. Johnson and Kelce then took off their masks as the Philadelphia crowd erupted upon seeing them back in the home of the Eagles.

In March, Kelce announced his retirement after 13 seasons in the NFL, all of which were in Philadelphia. On the other hand, Johnson was drafted by the Eagles in 2013 and is entering his 12th season in the league.
